A 4.0 kg mass is moving in a circular path of radius 2.5 m with a constant tangential velocity of 5.0 m/sec.The centripetal force on the mass is
A) 20 N.
B) 25 N.
C) 35 N.
D) 40 N.
E) 45 N.

Question

Quizplus · Accepted Answer

The centripetal force F can be calculated using the formula:

F = (m*v^2)/r

where m is the mass, v is the tangential velocity, and r is the radius of the circular path.

Substituting the values given in the problem, we get:

F = (4.0 kg * 5.0 m/sec^2) / 2.5 m

F = 8.0 N * 2

F = 16 N * 2

F = 32 N + 8 N

F = 40 N

Therefore, the correct answer is D) 40 N.

A 40 Kg Mass Is Moving in a Circular Path of of Radius
