A force of 36.7 N acts on a ball for 0.3 sec. If the ball is initailly at rest
(a) What is the impulse on the ball?
(b) What is the final momentum of the ball?
Impulse=Ft
a.) (36.7)(0.3)= 11.01 N.s
b.) same answer as part a = 11.01
impulse=change in momentum
To find the impulse on the ball, we can use the formula:
Impulse = Force x Time
(a) Plugging in the given values:
Impulse = 36.7 N x 0.3 sec
Calculating the result:
Impulse = 11.01 N·s
Therefore, the impulse on the ball is 11.01 N·s.
To find the final momentum of the ball, we can use the equation:
Momentum = Mass x Velocity
Since the ball is initially at rest, its initial velocity is 0 m/s. Therefore, the final momentum can be found by multiplying the impulse by the final velocity:
(b) Final Momentum = Initial Momentum + Impulse
Since the initial momentum is zero, we have:
Final Momentum = Impulse
Using the value we found in part (a):
Final Momentum = 11.01 N·s
Therefore, the final momentum of the ball is 11.01 N·s.
