A particle starts from rest and moves along the x-axis with a velocity that varies as v = √(100 + 4x) m s-1. The acceleration of the particle is:

A stone is dropped from a height h. It hits the ground with a momentum p. If the same stone is dropped from a different height h' such that the percentage increase in momentum is 41.4%, then h' = x h, where the value of x is:

A motorcycle starts from rest and travels 100 meters in 5 seconds with a constant acceleration. What is the magnitude of its acceleration?
