Question

Velocity versus time graph of a ball of mass 100 g rolling on a concrete floor is shown below. Calculate the acceleration and the frictional force of the floor on the ball? I WILL MARK AS BRAINLIEST PLS ITS URGENT

Answer 1

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.

Answer 2

Answer:
1000m/s
Explanation:
a=v-u/t
=80-0/8
=10
a=10
f=ma
=100*10
=1000
=1000m/s
