Which shows a 2 kg cart traveling at a constant speed in a horizontal circle of radius 3 m the magnitude of the centripetal force of the car is 24 N what is the speed of the cart

Respuesta :

Answer:

6m/s

Explanation:

Centripetal force is expressed according to the formula;

F = mv²/r

m is the mass of the body

v s the speed of the cart

r is the radius

Given

M = 2kg

r = 3m

Force F = 24N

Substitute into the formula and get v

24 = 2v²/3

24×3 = 2v²

72 = 2v²

v² = 72/2

v² = 36

v =√36

v = 6m/s

Hence the speed of the cart is 6m/s
