shutvik [7]

Answer:

A)   v = 40 m / s, B)   v_average = 20 m / s

Explanation:

For this exercise we will use the kinematics relations

         

A) the final velocity for t = 5 s and since the body starts from rest its initial velocity is zero

         v = vo + a t

         v = 0 + 8 5

         v = 40 m / s

B) the average velocity can be found with the relation

         v_average = vf + vo / 2

         v-average = 0+ 40/2

          v_average = 20 m / s

A man hits a golf ball (0.2 kg) which accelerates at a rate of 20 m/s2. What amount of force acted on the ball?
Delvig [45]
Newton taught us that    Force = (mass) x (acceleration)

Force  =  (0.2) x (20) = <em>4 newtons</em> .

Something to think about:  The ball can only accelerate while the club-face
is in contact with it.  Once the ball leaves the club, it can't accelerate any more,
because the force against it is gone.
