Because when an object is in motion it has kinetic energy
Answer:
3.416 m/s
Explanation:
Given that:
mass of cannonball
= 72.0 kg
mass of performer
= 65.0 kg
The horizontal component of the ball initially
= 6.50 m/s
the final velocity of the combined system v = ????
By applying the linear momentum of conservation:




v = 3.416 m/s
The answer is A. Bob (<span>object's length)

Given:
u(initial velocity)=0
a=5.54m/s^2
v(final velocity)=2 m/s
v=u +at
Where v is the final velocity.
u is the initial velocity
a is the acceleration.
t is the time
2=0+5.54t
t=2/5.54
t=0.36 sec
