Avolleyball is hit upward with an initial velocity of 6.0 m/s. calculate the displacement of the volleyball when its final velocity is 1.1 m/s upward.

1.78 m upward

Explanation:

We can find the displacement of the volleyball by using the SUVAT equation:

where, assuming upward as positive direction:

u = 6.0 m/s is the initial velocity

v = 1.1 m/s is the final velocity

a = g = -9.8 m/s^2 is the acceleration of gravity

d is the displacement

Solving the equation for d, we find:

And since it is positive, the displacement is upward.

the bal will not change its velocity.

f=ma newton

f=100x2.5=250n
