The friction force that a horizontal surface exerts on a 66-kg object is 17 N. If the initial speed of the object is20 m/s, what distance will it slide before coming to a stop? Calculate to one decimal

A 47,700 N car is traveling a 25 m/s.  The brakes are applied suddenly, and the car slides to a stop.  The average braking force between the tires and the road is 7100 N.  How far will the car slide once the brakes are applied?

An object is pushed in x and y directions with the force vector F=-230i+10j (N). The object weighs 20kg and goes through a displacement of r=-2i-5j (m). What would be the final velocity of the object?

A 2000kg truck starts at rest and reaches a speed of 15 m/s over a time period of 5s. What is the value of the force required to do this? Express answer in Newtons.

The elevator car, including passengers, has a mass of 1800 kg. Each floor of the building is separated by 4 m (i.e., the ground floor is at 0 m, the 1st floor is at 4 m, the 2nd floor is at 8 m, etc.) and the top floor is the 10th floor.  The elevator goes up from the ground floor, accelerates at a constant rate until it reaches the 1st floor at a speed of 1 m/s. It then maintains a constant speed, before decelerating (again at a constant rate) back to rest from the 9th to the 10th floor. a. Assuming that friction and drag forces are negligible, what is the maximum power output required for the elevator motor? b. How much work is done by the tension force (in the cable that pulls the elevator car up) from the ground floor to the 1st floor? From the 1st floor to the 9th floor? From the 9th floor to the 10th floor? c. How much work is done by the gravitational force from the ground floor to the 1st floor? From the 1st floor to the 9th floor? From the 9th floor to the 10th floor?

Mike pushes a box with a mass of 6.41 kg giving it an initial velocity of 2.49 m/s. The box comes to rest after sliding for 2.33 meters because of the frictional force exerted between the surface and the box. What is the frictional force on the box?

A lump of clay of mass 0.28 kg is dropped from a height of 10.8 m. The clay comes to a full stop  0.075 s after the moment it first touched the ground. What is the magnitude in newtons of the average force of impact that the clay experienced? Express your answer in two decimal places, with units of Newtons.

You throw a ball up with the initial velocity 2.5 m/s. What is the velocity of that ball when it reaches the half of the maximum height? The mass of the ball is 0.340 kg.
