Draw a motion diagram for a ball rolling down a ramp. assume the ramp is at 20˚ from horizontal.

answer:

just draw a ball rolling down a 20 degree slope? !

explanation:

Solution :

It is given that a system is released from rest where no slack is attached to the cable and the spring is unstretched.

Mass of the cart = 30 kg

Applying the conservation of energy of the system,

Loss of the gravitational potential energy (PE) = the energy stored in the spring.

i.e.,

       x = 1.98

Therefore the distance travelled by the 30 kg cart is 1.98 m.
