A cart of mass (8.4kg) is moving in a circular path of radius (2.0m), a centripetal force of (42N) is applied to the cart. What is the tangential velocity of the cart?

To find the tangential velocity of the cart, we can use the formula for centripetal force:

F = (m * v^2) / r

Where:

F = centripetal force

m = mass

v = tangential velocity

r = radius of the circular path

We can rearrange the formula to solve for the tangential velocity:

v = sqrt((F * r) / m)

Plugging in the values:

F = 42N

r = 2.0m

m = 8.4kg

v = sqrt((42 * 2) / 8.4)

v = sqrt(84 / 8.4)

v = sqrt(10)

v ≈ 3.16 m/s

So, the tangential velocity of the cart is approximately 3.16 m/s.
