Answer:
F = 0.483 N
Explanation:
Initial momentum,
Final momentum,
Time, t = 31 s
We need to find the force of a lead ball. We can use here the impulse momentum theorem.
F is force
So, the force is 0.483 N.
Answer:
As 28m/s = 28m/s
Explanation:
r = the radius of the curve
m = the mass of the car
μ = the coefficient of kinetic friction
N = normal reaction
When rounding the curve, the centripetal acceleration is
therefore
As 28m/s = 28m/s
