Answer:
100,048
Explanation:
K.E = 1/2 m (v)^2
K.E = 1^/2 * 74 * (52)^2
K.E = 100,048J =100.048kJ
Answer:
= = 140 m / s
Explanation:
This is a projectile launch, in this case the components of the initial velocity are seen
Since there is no rice in the X axis, so the velocity is vx, it must be constant, at all times
= = 140 m / s
The vertical component of velocity changes due to having applied the gravity fiate
= - g t
According to Newton’s second law acceleration= force/mass
So acceleration = 10/2
= 5m/s^2
Answer:
Explanation:
The situation of the system Ryan - merry-go-round is modelled after the Principle of the Angular Momentum Conservation:
