Ans: B
momentum = mass x velocity
= 0.50 x 5.0
= 2.5 kg m/s
Answer:
8.1Ns
Explanation:
Impulse is expressed as the product of Force and time
Impulse = Ft
F is the force = 180N
Get the time using the equation of motion
v = u+at
18 = 0+F/m(t)
18 = 180/0.45(t)
18 = 400t
t = 18/400 secs
Recall that;
Impulse = Ft
Impulse = 180×18/400
Impulse = 8.1Ns
Hence the impulse imparted to the ball is 8.1Ns
The change in velocity that occurs within an interval of time is known as ACCELERATION.
Acceleration is the rate of change of velocity with time. It is a vector quantity. The rate of change of velocity can be positive or negative. The positive change of velocity is called acceleration while the negative change in velocity is called deceleration.
