Answer:
Explanation:
The hand throwing ball moves on a circular path having radius r = .55 m
mass of ball m = .19 kg
velocity v = 70 mph
= 70 x 1600 / 60 x 60
= 31.11 m /s
centripetal force
= mv² / r
= .19 x 31.11² / .55
= 334.34 N

Answer:
the momentum of the child is 337.5 kg.m/s
Explanation:
Given;
velocity of the wagon, v = 1.5 m/s
the combined mass of the child and the wagon, m = 225 kg
The momentum of the child is calculated as;
P = mv
substitute the given values of mass and velocity to determine the momentum,
P = 225 x 1.5
P = 337.5 kg.m/s
Therefore, the momentum of the child is 337.5 kg.m/s
You have to find the calculate<span> the circumference first then you can just multiply the diameter by π, which is about 3.142. That gives you the distance for each </span>revolution<span>. Then you can multiply by the </span>number of revolutions<span> per minute.
