The tracks of Angel's flight extend 96.0 m along the side of a hill at an angle of 18.4 degrees with respect to the horizontal. If each car has a passenger with a mass of 70.0 kg, what is the total mechanical energy associated with the two passengers when the cars are ...

1.) a 5.0 kg stone slid up a frictionless ramp that has an incline of 25 degree. How long is the ramp if gravitational potential energy associated with the stone is 2.4 x 10^2 J. 2.) A pogo stick contains a spring with a constant force of 1.5 x 10^4 N/m. Suppose the elastic ...

A car moving at a speed of 48.0 km/h accelerates 100.0 m up a steep hill, so that at the top of the hill its sped is 59.0 km/h. if the car's mass is 1100 kg, what is the magnitude of the net force acting on it? i already know you have to change it to m/s but what do you do...

The most massive of the shikansen are the series 200 trains, yet they are among the fastest. Series 200 trains can reach speeds of 275 km/h. If a 16-car series 200 trains has a maximum kinetic energy of 2.78 x 10^9 J, what is its mass?

a girl pulls a wagon along a level path for a distance of 15.0 m. the handle of the wagon makes an angle of 20.0 degrees with the horizontal, the girl exerts a force of 35.0 N on the handle. Friction provides a force of 24.0 N. Find the net work done on the wagon.

if 2.0 J of work is done in raising a 180 g apple, how far is it lifted? equation used to figure this problem out?

The goliath beetle, can reach a mass of 0.080 kg. Suppose a goliath beetle is placed on a slope that makes an angle of 37.0 degrees with the horizontal. Find the acceleration of the beetle along the slope, assuming the slope is frictionless. If a force of 1.40 N upward along ...

An 8.0 kg bag of coin is being pulled upward by a rope rises 20.0 cm in 0.50 sec, starting from rest. Assuming the acceleration is constant, calculate the net force on the bag. what is the upward force on the bag exerted by the rope?
