Answer:
Its Moving at a constant Speed of 90km/hr
You can convert this speed to Meters/Second or Change it to Km/Second(Because we need our distance in Km)
So 90km/hr x 1/60 x1/60
=90km/3600sec
v=0.025km/sec
When an Object Moves at Constant Speed... Its displacement(distance) is given by
d=vt
given v=0.025km/sec
t=1sec
d=0.025km/sec x 1sec
d=0.025km.
The impulse given to the ball is equal to the change in its momentum:
J = ∆p = (0.50 kg) (5.6 m/s - 0) = 2.8 kg•m/s
This is also equal to the product of the average force and the time interval ∆t :
J = F(ave) ∆t
so that if F(ave) = 200 N, then
∆t = J / F(ave) = (2.8 kg•m/s) / (200 N) = 0.014 s
