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/s²

F=ma

F=1/20*-5

F=-1/4

F=-0.25N

Therefore,Force is -0.25N


Hope it helped,thnak you

Answer:

The force acting on the ball is -0.25 N.

Explanation:

Given that,

Mass = 0

According to velocity graph,

Initial velocity = 0

Final velocity v = 30 m/s

Time t = 6 sec

We need to calculate the acceleration

The acceleration is

Using equation of motion

v = u-at

Where, u = initial velocity

v = final velocity

a = acceleration

t = time

Put the value of u,v and t in the equation

30 =0-a\times6

a = -5\ m/s^2

Now. The force acting on the ball is

F = ma

F = 0.05\times(-5)

F = -0.25\ N

Hence, The force acting on the ball is -0.25 N.
