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
