Question

The velocity-time of a ball moving on the surface of a floor is showing in the figure find the force acting on the ball if the mass of the ball is 50 g

Answer 1

Answer:

so.., given

m = 50gm = 1/20kg

t = 6s

u = 30m/s

V = 0

F =?

a = V-u/t

a = 0-30/6

a = -30/6

a = -5m/s?

F = ma

F = 1/20 *-5

F = -1/4

F = -0.25N

Therefore, Force is -0.25N

Hope it helped, thank you
