Answer:
F = -2527.35 N
Explanation:
Given,
mass per unit time = 58.1 Kg/s
Speed of the water = 43.5 m/s
Final momentum = 0 kg/s
Force = Change in momentum
F = Final momentum - initial momentum
F = 0 - initial momentum
F = -2527.35 N
Hence, the Force exerted is equal to F = -2527.35 N
Answer:
60 m
Explanation:
After 3 seconds of travel at 20 m/s, the projectile is 3·20 = 60 meters horizontally from the cannon.
__
The vertical height after 3 seconds is 0.9 m, so the straight-line distance from cannon to target is √(60^2 +0.9^2) ≈ 60.007 meters.
When a heavy football player and a light one run into each other, does the lighter player really exert as much force on the heavy player s the heavy player exerts on the light one. Yes. The interaction between the two players, the force each exerts on the other have equal strength.
