A bobsleigh group is pushing their sled down the track at the start of a run. Four people all push on the sled, each with a force of 800N, for the first 10m of the run. The sled has a mass of 100 kg, and each group member has a mass of 80 kg. After they finish pushing, they all jump into the sled, and the sled continues to slide down the icy frictionless track. If the track is at a decline of 25◦ , how fast is the sled moving after traveling 20 m along the track?

A 845-kg car starts from rest on a horizontal roadway and accelerates eastward for 5.00 s when it reaches a speed of 30.0 m/s. What is the average force exerted on the car during this time?
At an instant when a soccer ball is in contact with the foot of the player kicking it, the horizontal or x component of the ball's acceleration is 700 m/s2 and the vertical or y component of its acceleration is 750 m/s2. The ball's mass is 0.32 kg. What is the magnitude of the net force acting on the soccer ball at this instant?
Dr. Miller is conducting an experiment. He has a stack of books on a table which is frictionless and flat. He applies a force F on the stack, and finds that it accelerates at 3.0 m/s². He then adds a book to the stack. This is a physics textbook that has a mass of 1.0 kg. He then applies the same force F on the stack and finds that now the stack accelerates at 2.0 m/s². What was the mass of the original stack of books? a) 1.0 kg Ob) 2.0 kg c) 3.0 kg O d) none of the above
Two boxes, Box A and Box B, are given an initial push and start moving at equal speed along a level, frictionless surface. The Box B has twice the mass of Box A. They both slide up the same frictionless incline plane. Which box rises to a greater height? Group of answer choices A) Box A rises to the greater height because it weighs less. B)The two objects rise to the same height. C) Box B rises to the greater height because it contains more mass. D) Box A rises to the greater height because it possesses a smaller amount of kinetic energy. E) Box B rises to the greater height because it possesses a larger amount of kinetic energy.
A car driver is stopped at a red light at an intersection. When the light goes green, she puts her foot on the accelerator, causing the engine to generate a varying driving force F(t) =430t + 860 t2 (with t in seconds, F in Newtons). It takes 3.00 seconds for the car to cross the intersection. The mass of the car (including passengers) is 700 kg. What is the speed of the car once it has crossed the interaction?
