A block is susoended from the end of a spring. The spring is hanging off the ceiling. An external force holds the block so that, initially, the spring is not stretched or compressed. When the block is released, it oscillates up and down between positions A and B. If the mass of the block is...

A package of mass m is released from rest at a warehouse loading dock and slides down a 2.44 m high frictionless chute to a waiting truck. Unfortunately, the truck driver went on a break without having removed the previous package, of mass 7.00m, from the bottom of the chute. Suppose the...

A 57.0 g tennis ball with an initial speed of 25.2 m/s hits a wall and rebounds with the same speed. The figure below shows the force of the wall on the ball during the collision. What is the value of Fmax, the maximum value of the contact force during the collision, if the force is applied for...

I totally understand your formula; I made the proper substitutions and it works. Thanks.

I've been thinking it over for some time. I can't get anywhere with it. I've done nothing.

Below is the first in a series of questions that build on one another; however I cannot solve this initial one. Any help is appreciated. A physics student on Planet Exidor throws a ball, and it follows the parabolic trajectory shown. The ball's position is shown at 1.00 s intervals until...

The problem is stated as follows: A sailboat is traveling east at 4.10 m/s. A sudden gust of wind gives the boat an acceleration a=(0.500 m/s2,40.0° north of east). What is the boat's speed 5.90 s later when the gust subsides? I've tried breaking it into component vectors, but no luck...

In a free-body diagram of a helicopter carrying a suspended object, what force exists to keep the helicopter aloft? Is there a normal force from the rotors? Any help would be appreciated.
