Question

Velocity versus time graph of a ball of mass 50 g rolling on a concrete floor is shown in figure. Calculate the acceleration and frictional force of the floor on the ball ​

Answer 1

Explanation:

u=0

v=80m/s

t=8s

a = slope of velocity and time graph

a = delta v/delta t ( delta v = v - u )

a = 80 - 0/8

=80/8

a = 10 m/s*s
