Find the centripetal force needed to keep an 60.0 kg rider traveling in a circle in the ride. Given:
m=
V = (from part a)
R =
Unknown:
F=?
Equation:
F= m (y^2) / r

Explanation:

Given that,

Mass of the rider, m = 60 kg

Let the radius of the circle, r = 30 cm = 0.3 m

Let the velocity, v = 20 m/s

We need to find the centripetal force needed to keep the rider in a circular path. It can be given by :

So, the required force is .

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is
