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
Where, u = initial velocity
v = final velocity
a = acceleration
t = time
Put the value of u,v and t in the equation
Now. The force acting on the ball is
Hence, The force acting on the ball is -0.25 N.
