If the mass of the egg is 0.90 kg its initial speed is 2.5 m/s and the time to stop is 0.20 s find the average force on the egg?
Apply kinematic equation
v-u = at
a = v-u/t = 0-2.5/0.20 = -12.5 m/s^2
the average force on the egg is
F = 0.9(12.5) = 11.25 N
If the mass of the egg is 0.90 kg its initial speed is 2.5 m/s and...
A 10-kg stone is thrown straight upward with the initial speed of 20.0 m/s. How high will it go if the average force of air resistance opposing its motion equals 0.20 N?
13. A model airplane of mass 0.90 kg flies with a constant speed of 20 m/s in a circle guided a rope 8 m long (a) [10 pts) Find the rope's tension needed to keep it in a circle. (b)[10 pts) Find the rope's tension if the rope length is doubled.
The model airplane has a mass of 0.90 kg and moves at constant speed on a circle that is parallel to the ground. The path of the airplane and the guideline lie in the same horizontal plane because the weight of the plane is balanced by the lift generated by its wings. Find the tension in the 17 m guideline for a speed of 19 m/s.
An electron of mass 9.11 10-31 kg has an initial speed of 2.85 105 m/s. It travels in a straight line, and its speed increases to 6.93 105 m/s in a distance of 5.50 cm. Assume its acceleration is constant. (a) Determine the force exerted on the electron. (b) Compare this force with the weight of the electron, which we neglected. F weight of the electron =
A 0.377-kg mass slides on a frictionless floor with a speed of 1.35 m/s. The mass strikes and compresses a spring with a force constant of 52.4 N/m. A. How far does the mass travel after contacting the spring before it comes to rest? B. How much time does it take for the spring to stop the mass?
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...
A mass of 1 kg and initial speed 10 m/s slides across a horizontal frictionless surface and hits a spring of force constant 200 N/m. How much will the spring be compressed from its relaxed length when the block will be at rest momentarily?
If its mass is 3.59×105 kg, its speed is 73.0 m/s, and the net braking force is 4.30×105N, what is its speed 8.00 s later? Express using THREE significant figures How far has it traveled in this time? Express your answer using three significant figures.
Consider a car with mass M. If the car has an initial speed of vo and a maximum braking force of Fb, write an expression for the stopping distance, i.e. the distance needed to stop if the full braking force is applied.Calculate the stopping distance for M = 1250 kg, vo = 14.0 m/s, and Fb = 2580 N.
