Well, the Train will have no movement since it is not moving, so a Sports car that is going 100 mph will have Momentum.
Answer:
10.36m/s
Explanation:
From the question we are given;
Distance S = 5.40m
Initial velocity v= 1.17m/s
Required
Final velocity of the diver
Using the equation of motion
v² = u²+2gS
v²= 1.17²+2(9.8)(5.40)
v² = 1.3689+105.84
v² = 107.2089
v = √107.2089
v= 10.36m/s
Hence the required velocity is 10.36m/s

Answer: 5 m, 2 s
Explanation:
gravity is roughly 10 m/s²downward
That means in one second, the velocity will have been reduced to zero
The average speed is (10 + 0) / 2 = 5 m/s
h = vt = 5(1) = 5 m
It will take as long to fall back to the thrower from rest so total flight is 1 + 1 = 2 s
