A 45 kg cart is pulled along by a rope that applies a 120 N force at 30 degree. How much work is done by the 120 N force as the cart moves 7 m? If the friction force on the cart is 50 N, how much work is done by the friction force? How much work is done by gravity? What is the net work done on the cart? If the initial speed of the cart was 5 m/s,...

A 2000 kg car strikes a wall at 15 m/s and comes to a stop in .15 seconds. With how much force did the car strike the wall? Please show all work.
A 1000-kg car moves as speed from 10 m/s to 30 m/s in 20 seconds. What is the average speed? What is the acceleration? What is the average force acting upon it? If the car turns along a circle at 5 m/s around a curve 30 meters in radius, how big the centripetal force is needed?
7. (20 pts) A force of 50 N is used to move a 5 kg box 30 m across a level floor. a. How much work was done on the box? b. If the movement takes 10 seconds, what is the average velocity of the box during the move? c. What is the average kinetic energy of the box during the move? d. What is the change in potential energy as a result of this move?
An electric vehicle starts from rest and accelerates at a rate of 2.2 m/s2 in a straight line until it reaches a speed of 22 m/s. The vehicle then slows at a constant rate of 1.0 m/s2 until it stops.(a) How much time elapses from start to stop (in seconds)?(b) How far does the vehicle travel from start to stop (in meters)?
QUESTION 1 15 points Save An Calc?late the force (in N) needed to bring a 1000 kg car to rest from a speed of 90.0 km/h in a distance of 115 m (a fairly typical distance for a non-panic stop).
1.) A 1000-kg car moves as speed from 10 m/s to 30 m/s in 20 seconds. What is the average speed? What is the acceleration? What is the average force acting upon it? If the car turns along a circle speed at 5 m/s around a curve 30 meters in radius, how big the centripetal is needed? 2.) For two objects with masses 100 kg and 500 kg to be 20 meters apart, find the gravity between them
