An inclined plane is used to lift a box into a moving truck. The ramp is 6m long and 1.5m from the ground. What is the mechanical advantage of the inclined plane?

Given :

An inclined plane is used to lift a box into a moving truck. The ramp is 6 m long and 1.5 m.

To Find :

The mechanical advantage of the inclined plane.

Solution :

Mechanical advantage, M.A of an inclined plane is given by :

Putting given values in above equation, we get :

Therefore, the mechanical advantage of the inclined plane is 4.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
