A 60 g tennis ball with an initial speed of 37 m/s hits a wall and rebounds with the same speed. (Figure 1) shows the force of the wall on the ball during the collision.

What is the value of Fmax, the maximum value of the contact force during the collision?



Answer :

The contact force during the collision is 0N.

Given

mass = 60 g = 0.06 kg

Speed = 37m/s

To find the value of Fmax, the maximum value of the contact force during the collision

[tex]Fmax=m a[/tex]

a means acceleration i.e. rate of change of velocity.

[tex]a=\frac{dv}{dt}[/tex]

Since in the question there is uniform speed maintained.

[tex]Velocity = constant\\Acceleration = 0[/tex]

[tex]Fmax= 0.06 * 0\\F= 0[/tex]
