Answer should be netween 200-400J
A boy in a wheelchair (total mass 53.5 kg) has speed 1.40 m/s at the crest of a slope 230 m high and 12.4 m long. At the bottom of the slope his speed is 7.00 m/s. Assume air resistance and rolling resistance can be modeled as a constant friction force of 41.0 N. Find the work he did in pushing forward on his wheels during the downhill ride 740 02 Your response differs from...

A 1.60-kg object is held 1.40 m above a relaxed, massless vertical spring with a force constant of 305 N/m. The object is dropped onto the spring. (a) How far does the object compress the spring? m (b) Repeat part (a), but this time assume a constant air-resistance force of 0.600 N acts on the object during its motion. m (c) How far does the object compress the spring if the same experiment is performed on the Moon, where g...

A 1.30 kg object is held 1.35 m above a relaxed, massless vertical spring with a force constant of 300 N/m. The object is dropped onto the spring. (a) How far does the object compress the spring? m (b) Repeat part (a), but now assume that a constant air-resistance force of 0.650 N acts on the object during its motion. m (c) How far does the object compress the spring if the same experiment is performed on the moon, where g = 1.63 m/s2 and air resistance is neglected? m

A 1.80-kg object is held 1.15 m above a relaxed, massless vertical spring with a force constant of 315 N/m. The object is dropped onto the spring. (a) How far does the object compress the spring? 0.396x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m (b) Repeat part...

can someone solve all parts please
The 30 kg mass has a speed of 2m/sec in the position shown and a constant force of 20N is applied on it as shown and this force is acting on the mass for another 3 meters down the incline and then disappears. After another 7 meters the mass hits a loss of energy at impact to spring and Dynamic Friction coefficient is 0.25 Spring Constant is 200 kN/m A) What is the speed...
A m= 2.00 kg block is pushed against a spring with negligible mass and force constant k= 300. N/m
A m= 2.00 kg block is pushed against a spring with negligible mass and force constant k= 300. N/m, compressing it d= 0.250 m. When the block is released, it moves along a frictionless, horizontal surface and then up an incline with slope 37.0° and a coefficient of kinetic friction of 0.320. A)What is the speed of the block as it slides along the horizontal surface after having left the spring?B) How far does the object travel up the incline before...

1. A Cessna 206H has a mass of 1000 Kg, a takeoff speed of 34 m/s (about 67 kn) and its propeller generates a power of 224 KW (224 kilowatts or 300 hp). Assuming no air drag and full, constant power, calculate the time it takes the Cessna to reach the takeoff speed. 2. Calculate the Kinetic Energy KE and the Angular Momentum L of a rigid object with a moment of inertia 0.4 Kgm2 spinning around a fixed axis...

please solve both. thank
you!
A mass of 1.25 kg stretches a spring 0.06 m. The mass is in a medium that exerts a viscous resistance of 56 N when the mass has a velocity of 2 . The viscous resistance is proportional to the speed of the object. Suppose the object is displaced an additional 0.03 m and released. Find an function to express the object's displacement from the spring's equilibrium position, in m after t seconds. Let positive...

1. A 67-kg base runner begins his slide into second base when he is moving at a speed of 4.5 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base. (a) How much mechanical energy is lost due to friction acting on the runner? (b) How far does he slide? 2. A 0.32-kg stone is held 1.4 m above the top edge of a...

I need help with the last three questions
the Loop A mass m -82 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R 7.8 m and finally a flat straight section at the same height as the center of the loop (17.8 m off the ground). Since the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it...
