physics
A 1100-kg car is being driven up a 4.0° hill. The frictional force is directed opposite to the motion of the car and has a magnitude of f = 518 N. A force is applied to the car by the road and propels the car forward. In addition to these two forces, two other forces act o...

A car accelerates uniformly from rest to 21.0 m/s in 6.1 s along a level stretch of road. Ignoring friction, determine the average power required to accelerate the car if the weight of the car is the following. A) 8.0e3N B) 1.2e4N

When I did this I got the answer 12.91 prior to you responding to me and when I tried the way you said I recieved the same answer but our software is telling me that its wrong and i tried twice.

A baseball (m = 151 g) approaches a bat horizontally at a speed of 39.8 m/s (89 mi/h) and is hit straight back at a speed of 45.7 m/s (102 mi/h). If the ball is in contact with the bat for a time of 1.05 ms, what is the average force exerted on the ball by the bat? Neglect the...

A car (mass=1100kg) is traveling at 32m/s when it collides head on with a sport utility vehicle (mass=2500kg) traveling in the opposite direction. In the collision, the two vehicles come to a halt. at what speed was the sport utility vehicle traveling.

physics
A two staged rocket moves in space at a constant velocity of 4900m/s. The two stages are then separated by a small explosive charge between them. Immediately after the explosion the velocity of the 1200kg upper stage is 5700m/s in the same direction as before the explosion. Wh...
