Question

Physics / MAth help

Answer 1

IIRC it actually doesn't matter what the slope is because the kinetic energy is dependent on the potential energy at the beginning

U = mgh = K

@sillybilly123 can you check this

Answer 2

Yeah this is just a simple case of conservation of energy. Since the slope is friction less, energy is conserved. Therefore,

PE = KE

Solve for potential energy gravitational and you should be good.

Answer 3

SO A?

Answer 4

Yes

Answer 5

Thank you
