Question

Answer these please and explain. (100 points)

1.A piece of candy dropped from a tall building has gained a velocity of 52.6 m/s. how long has the candy been falling with an acceleration of 9.8m/s2?


2.An object traveling 200m/s slows down to 50 m/s in 5 seconds. calculate the acceleration of the object


3.a runner is accelerating at a rate of 30 m/s2 How fast will he be going 5 seconds after he starts?

Answer 1

Step-by-step explanation:

1.) V = V₀ + at

52.6 m/s = 0 + (9.8 m/s²)t

t = (52.6 m/s)/(9.8 m/s²) = 5.37 s

2.) a = ΔV/Δt = (50 m/s - 200 m/s) / 5 s = -30 m/s²

3.) V = V₀ + at

V = 0 + (30 m/s²)(5 s) = 150 m/s

This assumes he starts from rest. Also, no human can run 150 m/s. Are you sure the given a is 30 m/s²? You may want to double check.
