Exercise 6.41 A force F is applied to a 2.0 kg, radio-controlled model car parallel to the z-axis as it moves along a straight track. The 2-component of the force varies with the -coordinate of the car as shown in the figure (Figure 1). Part A 0 to 3 = 3.0 m. Calculate the work done by the force F when the car moves from Express your answer with the appropriate units. C: Å * O ? W0-3.0 = Value...

A truck on a flat road accelerates from rest at a constant rate and covers a distance of 100 m in 6 s. The mass of the truck is 900 kg. What is the acceleration of the truck? What is the net force on the truck? The truck is now loaded with heavy equipment and has a NEW total mass of 1300 kg. If the same net force is applied to the car as calculated above, then what would be...

1. A roller coaster has a 300 kg car. Assume the track is frictionless. a) The car starts at a speed 20 m/s on a horizontal track. It then goes through a circular loop. What is the speed of the car when it is at the top of the loop, h = 10 m above the horizontal track? b) What is the normal force applied from the track at the point? Does this force point upward or downward? Assume the...

1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...

1. John (who is 95 kg) drives his car over an absurdly large half-circle speedbump with a radius of 5 meters. Given that his normal weight is 930 N and his apparent weight at the top of the speed-bump was 246 N, how fast did he drive over the speed bump? 2. When working in circular motion problems, what do we define as always being the positive direction? 3. When in circular motion, the net force points in what direction?...
