Answer:
v=s/t
s=vt
t=s/v
t=(120×10‐³)/172.8
(the distance meters has been changed to kilometres)
t=1/1440 hrs
Given ,
Answer:
4611.58 ft/s²
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 32.174 ft/s²
Equation of motion


Magnitude of acceleration while stopping is 4611.58 ft/s²
Momentum of an object = (its mass) x (its speed) .
Since speed is a factor of momentum, an object that
isn't moving doesn't have any.
-- The moving player has momentum.
-- The stationary one doesn't.
