A 2.0-N force acts horizontally on a 10-N block that is initially at rest on a horizontal surface. The coefficient of static friction between the block and the surface is 0.50. What is the magnitude of the frictional force that acts on the block? A) 0 N B) 2 N C) 5 N D) 8 N E) 10 N
4. A constant 80-N force acts on a 5.0 kg box. The box initially is moving at 20 m/s in the direction of the force, and 3.0 s later the box is moving at 68 m/s. Determine both the work done by this force and the average power delivered by the force during the 3.0-s interval. Ans: W=11kJ, P= 3.5kW
An object of mass 0.53 kg is initially at rest. When a force acts on it for 2.9 ms it acquires a speed of 14.1 m/s. Find the magnitude (in N) of the average force acting on the object during the 2.9 ms time interval. N
An object of mass 0.61 kg is initially at rest. When a force acts on it for 2.9 ms it acquires a speed of 14.8 m/s. Find the magnitude (in N) of the average force acting on the object during the 2.9 ms time interval.
A 6.4 kg crate is pushed with a constant horizontal force of 22 N on a flat surface with kinetic friction coefficient µk = 0.25. If it starts from rest, what is its speed after 12 meters? (Use the work-energy theorem; remember that the formula uses the total net work of all forces present).
An initially stationary 2.6 kg object accelerates horizontally and uniformly to a speed of 23 m/s in 5.0 s. (a) In that 5.0 s interval, how much work is done on the object by the force accelerating it? What is the instantaneous power due to that force (b) at the end of the interval and (c) at the end of the first half of the interval?
An initially stationary 4.1 kg object accelerates horizontally and uniformly to a speed of 9.4 m/s in 3.6 s. (a) In that 3.6 s interval, how much work is done on the object by the force accelerating it? What is the instantaneous power due to that force (b) at the end of the interval and (c) at the end of the first half of the interval?
A constant 74.6-N force acts on a 4.99-kg box. The box initially is moving at 15.1 m/s in the direction of the force, and 2.93 s later the box is moving at 76.5 m/s. Determine the work (in J) done by this force. You may assume that the box experiences constant acceleration, but do not assume that only one force acts on the box.
