Question 63
Easy

A parcel slides down a smooth delivery chute from point A to point B.

A parcel is shown at the top of a sloped delivery chute (point A) at a vertical height h. It slides down the ramp to the bottom (point B) on the floor.

The gravitational potential energy of the parcel decreases by 147 J.

The mass of the parcel is 5.0 kg.

Calculate the vertical height, hhh, of the chute.

Use g=9.8 N/kgg = 9.8 \text{ N/kg}g=9.8 N/kg.

Use the equation:

change in gravitational potential energy=mass×gravitational field strength×change in height \text{change in gravitational potential energy} = \text{mass} \times \text{gravitational field strength} \times \text{change in height} change in gravitational potential energy=mass×gravitational field strength×change in height
