1. The problem statement, all variables and given/known data

An object moving at a constant speed of 31 m/s is making a turn with a radius of curvature of 4 m (this is the radius of the "kissing circle"). The object's momentum has a magnitude of 87 kg·m/s.

What is the magnitude of the rate of change of the momentum?

What is the magnitude of the net force?

2. Relevant equations

p = mv

[tex]\Delta[/tex]p = F_{net}[tex]\Delta[/tex]t

dp/dt = magnitude of V / R (sry dont know how to put that in latex)

3. The attempt at a solution

Question 1: Velocity divided by radius? Using the 3rd equation, but the units dont check out.

I am lost

Question 2: How do I find t, and afterwards, the answer would be F_{net}= 87 (change in momentum) * t (change in time)
