I don’t see any answer choice but the best way is asking questions about the natural phenomenon, making hypothesis, and predicting the consequences in the hypothesis.
Answer:
Explanation:
30 rev/min (2π rad/rev) / (60 s/min) = π rad/s
α = Δω/t = (0 - π)/3 = π/3 rad/s²
θ = ½αt² = ½(π/3)3² = 1.5π radians
θ = 1.5π rad/2π rad/rev = 0.75 rev

Answer:
50.3 m/s²
Explanation:
Centripetal acceleration is:
a = v² / r
where v is velocity and r is radius.
First, calculate the velocity. Velocity is distance divided by time. The distance is the number of circumferences traveled by the ball.
v = x / t
v = (15.0 × 2π × 0.230 m) / 6.37 s
v = 3.40 m/s
Therefore:
a = (3.40 m/s)² / 0.230 m
a = 50.3 m/s²
Locomotion is the ability to move from place to place, or the act of doing so.
