Atruck is balanced on an incline as shown the angle of inclination id 34.1 degrees, the outer part of the large pulley has a radius of 3r and the inner part of the large pulley has a radius of r. find the mass m needed to balance the 1320 kg truck on the incline

i would say the answer is food.

hope this !

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

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.
