Question

A Skier starting from rest rolls down a 35.0 m ramp. When he arrives at the bottom of the ramp his

Answer 1

The acceleration is  1.55 m/s^2 while is component that is parallel to the ground is 0.775  m/s^2.

What is acceleration?

The term acceleration is the rate of change of speed. Given that the distance covered is 35.0 m and the final velocity is 10.43 m/s it the follows that;

v^2 = u^2 + 2as

u = 0 because he started from rest

v^2 = 2as

a = v^2/2s

a = (10.43 m/s)^2/2 * 35.0 m

a = 1.55 m/s^2

The component of this acceleration which is parallel to the ground is;

ax = a sin θ

ax =  1.55 m/s^2 cos 60

ax = 0.775  m/s^2
