Question

a stone is dropped from the top of a tower of height 100m. the stone penetrates in the same direction through a distance of 2 m. calculate tge retardation of the stone

Answer 1

initial velocity = 0
final velocity = 2m
distance = 100 m
retaradation =?

using equation

2as = v^2 - u^2

2(a)(100)=4-0
200a = 4
a = 4÷200
a = 50


retaradation is 50
