1. A 4.0 kg particle is moving at a velocity v = V2î – V2ĵ + 3k m/s. (a) (b) What is the particle's kinetic energy at this moment? What is the net work done on the particle if its velocity changes to - V2î + 3k m/s? V = - Assume that a force in the x y plane acts on the particle to slow it down (imagine (c) that this force is a type of friction). Will the particle's kinetic energy become zero under the influence of this force? Explain your answer.
The drawing shows two boxes resting on frictionless ramps. One box is relatively light and sits on a steep ramp. The other box is heavier and rests on a ramp that is less steep. The boxes are released from rest at A and allowed to slide down the ramps. The two boxes have masses of 13 and 37 kg. If A and B are 4.5 and 1.0 m, respectively, above the ground, determine the speed of (a) the lighter box and (b) the heavier box when each reaches B.

A spring (k = 600 N/m) is placed in a vertical position with its lower end supported by a horizontal surface. The upper end is depressed 20 cm, and a 4.0-kg block is placed on top of the depressed spring. The system is then released from rest. How far above the point of release will the block rise? 46 cm 31 cm 36 cm 41 cm 20 cm
A force →F=(9.10N)ˆi+(3.10N)ˆj+(8.70N)ˆk acts on a 5.00 kg mobile object that moves from an initial position of →di=(9.30m)ˆi+(6.20m)ˆj+(6.40m)ˆk to a final position of →df=(6.00m)ˆi+(1.20m)ˆj+(9.50m)ˆk in 5.30 s. Find (a) the work done on the object by the force in the 5.30 s interval, (b) the average power due to the force during that interval, and (c) the angle between vectors →di and →df.
Two blocks with masses 0.342 kg (A) and 0.719 kg (B) sit on a frictionless surface. Between them is a spring with spring constant 27.7 N/m, which is not attached to either block The two blocks are pushed together, compressing the spring by 0.270 meter, after which the system is released from rest. What is the final speed of the block A? (Hint: you will need to use both conservation of energy and conservation of momentum to solve this problem).

A horizontal spring with spring constant 85 N/m extends outward from a wall just above floor level. A 8.5 kg box sliding across a frictionless floor hits the end of the spring and compresses it 6.5 cm before the spring expands and shoots the box back out. How fast was the box going when it hit the spring? How fast was the box going when it hit the spring? v=
