4. The power provided by a force can also be written as P = dW /dt = F · d7/dt = F .ö. A force F = (3i – 2j + 6k)N is applied to an object moving with a velocity i = (2î – 3k) m/s. a. What is the power provided by this force? Does the object speed up or slow down or neither, if this force is the only unbalanced force acting on the object? b. Consider a force that is always perpendicular to the velocity. Does the object speed up or slow down or neither, if this force is the only unbalanced force acting on the object?
1. Compute for W1 to pull he block up 2. Compute for W1 to keep the block in position 3. If the surface is lined with rubber ( M= 0.6 ). How much weight needs to be reduced to keep the block stationary 50kg U =0.4 450 Wi
Computation. A block is released from rest at the top of a 47-m long frictionless ramp inclined at 34° above the horizontal. What is the block's speed at the bottom of the ramp? v= m/s Record your numerical answer below, assuming three significant figures. Remember to include a "-" if/when necessary.
A 3.50 kg block is pulled up a frictionless inclined plane by a 60.0 N force that is parallel to the plane, starting from rest.The normal force on the block from the plane has magnitude 15.2 N.What is the block's speed when its displacement up the ramp is 3.40 m? Number i Units
Question 10 A 10.0 kg child on a 5.0 kg sled, starting from rest, goes down a frictionless hill with a height of 3.25 m.

QUESTION 28 You push a 80-kg file cabinet to the right on a frictionless horizontal surface with a force of 175 N from rest, the cabinet moves a distance of 12 m. What is the final speed of the cabinet, in m/s? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
18. Two toy cars are pushed to the right. The first toy car is made of plastic, and has a low mass. The second toy car is made of metal, and has a larger mass than the first car. Both cars are pushed with the same force for the same distance. The friction on both cars is so small that it can be ignored. At the end of the push, how do the kinetic energies of the cars compare? a. The first, lower mass car has a larger kinetic energy. b. The second, higher mass car has a larger kinetic energy. c. The kinetic energies of the two cars are equal. d. Neither car has kinetic energy after the push is applied.
