A child on a sled starts from rest at the top of a 15° slope. If the trip to the bottom takes 10.2 s how long is the slope? Assume that frictional forces may be neglected.

Explanation:

Given data

Angle α=15°

time taken t=10.2 s

To find

Length of slope

Solution

From ΣF=ma

hail is a solid form of precipitation composed of large, layered ice particles called pellets that often have spherical shapes. this phenomenon occurs during thunderstorms in the could type known as cumulus
