Question

1. A 30-kg child is spinning horizontally in a ride with a

centripetal acceleration of 10 m/s/s. How many newtons

of centripetal force are acting on her?

Answer 1

To find the centripetal force acting on the child, multiply the mass of the child (30 kg) by the centripetal acceleration (10 m/s²), resulting in 300 newtons of force.

Step-by-step explanation:

To calculate the centripetal force acting on the child, we can use the formula F = m × a, where F is the centripetal force, m is the mass of the child, and a is the centripetal acceleration. Given that the child's mass is 30 kg and the centripetal acceleration is 10 m/s2, we simply multiply these values to get the force.

So, F = 30 kg × 10 m/s2 = 300 N. Hence, there are 300 newtons of centripetal force acting on her.

Answer 2

300newtons of centripetal force

Step-by-step explanation:

Force is mathematically expressed as mass×acceleration due to gravity

Mass of child equals 30kg

Acceleration due to gravity equals 10m/s²

Force is unknown so we restate formula & fix in the quantities

∴Force equals mass×acceleration due to gravity

(representing force by f,mass by m & acceleration...gravity by g)not always necessary

So f equals m×g(fix in values)

f equals 30kg×10m/s²

f equals 300newtons

∴The centripetal force acting on her is 300newtons
