During an attemp of croquet game, a 0.52 kg ball at rest on the grass is hit by a mallet with an average force of 190 N, if the mallet is in contact with the ball for
, Whay is the speed of the ball just after being hit?
According to Newton's second law of motion, the force
exerted on an object is directly proportional to its mass
and acceleration
:
(1)
On the other hand, acceleration is defined as the variation of velocity
in time
:
(2)
Substituting (2) in (1):
(3)
Where:
Isolating the velocity
from (3):
(4)
Finally:
