Question

At the start of a race, a four-man bobsled team pushes their sled as fast as they can along a 50 m flat starting stretch. The net force that the four men together apply to the 325 kg
bobsled is 80.093 N directed at 15 degrees below the horizontal. As they push, 60 N of kinetic friction opposes them. What is the speed of the sled right before the team jumps on
the sled?

You push a 43-kg file cabinet to the right on a frictionless horizontal surface with a force of 225 N from rest, the cabinet moves a distance of 7.3 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.
Sara throws a baseball to Janice. The baseball has a mass of 0.142kg. It is 1.1m above the ground, moving at 15m/s when sara lets go of it. Ignore the effects of air resistance. The baseball is moving horizontally at 13m/s when it reaches maximum height. Calculate the maximum height reached by the baseball.
Sometimes, steep roads going down have a small safety road by the side that goes up, which vehicules can use in an emergency, to slow down. A 3362.6 kg truck has lost its brakes coming down a mountain. Fortunately, there is a ramp of thick gravel inclined at 14 degrees that the driver can use to stop the truck. The truck hits the ramp moving at 20.58 m/s and then travels 35.6 meters up the ramp before it comes to a stop. What work is done by the gravel to stop the truck?

5. A top WNBA player can jump about .7 meters off the ground. If her mass is 50 kg, what force must she exert against the ground? Assume she crouches a distance of .2 metes prior to jumping, and thus the upward force has this distance to act before leaving the ground. 6. A block is given an initial speed of 4 meters per second up the 0 = 22° plane shown below. Ignoring friction, %3D (a) how far up the plane will it go?

A child and sled with a combined mass of 32.4 kg slide down a frictionless hill, starting at the top. The sled starts from rest and acquires a speed of 6.9 m/s by the time it reaches the bottom of the hill. What is the height (in m) of the hill?
A bowling ball is dropped from the top of a building that has a height of h = 155 m. 1.Assuming air resistance is negligible, what is the ball's speed, vf in m/s, when it strikes the ground? 2.If drag produces an opposing force of 10 N while the ball's falling, what is the ball's speed, vf in m/s, when it strikes the ground? Assume the ball has a mass of 5 kg. 3.A different ball was dropped and the final speed was measured to be vf = 7.5 m/s while the drag force was measured to be 50 Newtons. What is the mass of this ball in kg?
A horizontal force of 80.0 N is applied to a 5.00 kg block as the block slides a distance of 0.800 m along a horizontal floor. The coefficient of kinetic friction between the floor and the block is 0.500. If the block is initially at rest, how fast is it moving at the end of the displacement?
