Answer:
F = - K x force is opposed to direction of extension
F = -100 N / m * .5 m = -50 N
There are two main reasons why a bouncing ball rise to a lower height with each bounce: 1) because every time it hits the ground it encounters friction, which slows it down, and every time it rises from the ground it encounters air resistance.
Answer:
0.6 seconds
Explanation:
The time to fall from height h is ...
t = √(2h/g)
t = √(2(1.86 m)/(9.8 m/s^2)) ≈ √0.3796 s ≈ 0.616 s
It would take about 0.6 seconds for the projectile to hit the ground.
Answer:
the total travled is 2.75
Explanation:
because if you divide 110 by 40 you get 2.75
