A roller coaster is moving with 30 ms^-1 on a circular track of radius 30m. The net mass of coaster + passengers is 'm' the centripetal force acting on it is?

Answer: 30m

The centripetal force (F) acting on the roller coaster is given by the formula:

F = (m × v^2) / r

Where:

m = net mass of coaster + passengers

v = velocity = 30 m/s

r = radius of the circular track = 30 m

Substituting the values, we get:

F = (m × (30)^2) / 30

= (m × 900) / 30

= 900m / 30

= 900m

So, the centripetal force acting on the roller coaster is 900m.
