A hovercraft of mass 73.0 kg can move on a horizontal surface, the x-y plane. A single unbalanced force acts on the hovercraft, but the size of the force is unknown. The hovercraft initially has a velocity of 7.0 m/s in the positive x direction and some time later has a velocity of 8.0 m/s in the positive y direction. How much work is done on the hovercraft by the force during this time?

The only force acting on a 3.3 kg canister that is moving in an xy plane has a magnitude of 6.6 N. The canister initially has a velocity of 3.7 m/s in the positive x direction, and some time later has a velocity of 4.2 m/s in the positive y direction. How much work is done on the canister by the 6.6 N force during this time?
he only force acting on a 4.9 kg canister that is moving in an xy plane has a magnitude of 5.9 N. The canister initially has a velocity of 3.0 m/s in the positive x direction, and some time later has a velocity of 7.5 m/s in the positive y direction. How much work is done on the canister by the 5.9 N force during this time?
QUESTION 5 A mass of 12 kg is placed on a horizontal surface with friction with a coefficient of static friction of 0.81 and coefficient of kinetic friction of 0.44. A force of 13 Newtons is applied in the -y direction and a force of 16 Newtons is also applied in the -y direction. Another force is applied in the +x direction (see sketch). The force applied in the +x direction is increased until it is 1.9 times the force...

Blocks A (mass 4.50 kg) and B (mass 15.00 kg) move on a frictionless, horizontal surface. Initially, block B is at rest and block A is moving toward it at 1.00 m/s.The blocks are equipped with ideal spring bumpers. The collision is head-on, so all motion before and after the collision is along a straight line. Let +x be thedirection of the initial motion of AFind the maximum energy stored in the spring bumpers and the velocity of each block...
