The speed of the skier sliding down the mountain in 3 seconds increased from 0.2 m / s to 2 m / s. Determine the acceleration of the skier.
Given:
t = 3 s
V (0) = 0.2 m / s
V = 2 m / s
a =?
Decision:
a = (V-V (0)) ÷ t
a = (2-0.2) ÷ 3
a = 1.8 ÷ 3
a = 0.6 m / s ^ 2
Answer: the acceleration of the skier is 0.6 m / s ^ 2
