Question

A 111 kg dolphin swims in a circle with a radius of 7 m at a velocity of 6 m/s. What is the centripetal force acting on the dolphin?

A) 5034 N
B) 1415 N
C) 2646 N
D) 987 N

Answer 1

The centripetal force acting on the dolphin is approximately 5034 N.

Step-by-step explanation:

To determine the centripetal force acting on the dolphin, we can use the formula:

F = m * v^2 / r

Where:
m = mass of the dolphin = 111 kg
v = velocity of the dolphin = 6 m/s
r = radius of the circle = 7 m

Substituting the given values into the formula:

F = 111 * (6)^2 / 7

F ≈ 5034 N

Therefore, the centripetal force acting on the dolphin is approximately 5034 N (Option A).
