The cell would die if it stopped using energy
It would take the bicyclist 9 seconds to move 36m.
Answer:
B. 25 m/s/s
Explanation:
Centripetal acceleration is the square of the tangential velocity divided by the radius of curvature.
a = v² / r
Given v = 10 m/s and r = 4 m:
a = (10 m/s)² / 4 m
a = 25 m/s²
a) uniform velocity
b) zero or no acceleration
c) (see picture)
