Question

a ball of mass 50 G rolling on a concrete floor. calculate the acceleration and the friction force of the floor on the ball​

Answer 1

Explanation:

We know that Acceleration a=

t

v−u

=

8−0

0−80

=−10ms

−2

Now, Force=ma

m=50g=

1000

50

kg

So, F=ma=

1000

50

×10=0.5N

frictional force oppose the motion, so it is taken as positive with direction opposote to velocity. please mark me brainiest.
