3. A block of mass m = 6.2 kg, moving on a frictionless surface with a velocity of -6.5 m/s to the right, collides with a block of mass M at rest, as shown in the figure. After the collision, the 6.2-Kg block recoils with a velocity of f =0.70 m/s to the left. If the blocks are in contact for 0.30 s, what is the magnitude of the average force on the 6.2-kg block, while the two blocks are...

2. An object of 5 kg is released from rest 1000 meters above the ground level and allowed to fall under the influence of gravity. Assuming that the force due to air resistance is proportional to the velocity of the object with proportionality constant k = 50 kg/sec determine the formula for the velocity of the object 3. A rocket having an initial mass mo kg is launched vertically from the surface of the Earth. The rocket expels gas at...

3) A mass of 5 kg is resting on a horizontal, frictionless surface. Force 1 is applied to it at 20 degrees below the horizontal in the -x direction, force 2 has a magnitude of 88 N and is applied in the +x direction , and force 3 has a magnitude of 25 N and is applied vertically downwards. When these forces are applied, the normal force acting on the mass is twice the amount of its weight. Also, when...

a 2.0 kg mass moves along a frictionless horizontal surface at a speed of 5.0 m/s. The mass encounters a 30 degree inclined surface with a constant friction force of 1.5 N. At 1 m high (vertical) the surface levels off and is again frictionless. the mass then encounters a spring with k=10 N/m a) how far is the spring compressed after the mass comes to rest? b) how far down the inclined plane will the mass move after bouncing...

Problem 1: An object with mass m, = 2 kg slides down a frictionless incline that makes a 25° with the horizontal (as in the figure). At the bottom of the incline, object 1 continues to travel along the rough surface with the = 0.4. Object 2, m, = 5 kg is d = 3 m away from the bottom of the incline. Object 2 is initially at rest. The height of the incline is h = 4m. h 0...

Two objects are sitting on a frictionless surface. Object 1 has mass mi, while object 2 has twice as large a mass, m2=2mı. You push with force F on object 1 for 3 s, and then push on object 2 for the same length of time with the same force F. A. After the push, what is the ratio of the momentum of object 2 to the momentum of object 1? Explain your answer. [5] a) 4/1 b) 2/1 c)...

An object of 3 kg mass is at rest on a smooth frictionless surface. It is struck by a bullet travelling horizontally at 370 m/s. The bullet is embedded in the object and they move off together at 4.27 m/s. Assuming motion in a straight line, find the mass of the bullet. (Could you include a drawing aswell)

Object A of mass M is initially at rest on a flat, smooth
frictionless surface. Object B, which has twice the mass of A, is
traveling with speed V before it collides elastically with A.
Immediately after the collision, both objects move off at angles
(theta)>0 with respect to the original direction of B. Calculate
the value of the angle.
[Hint: Note that the collision is elastic.] .
