For volleyball a dead ball is, A ball not in play following a point, side-out or any other decision of the referee temporarily suspending play.
For basketball the ball is considered dead, such as when a foul has been committed and called by a referee, a foul shot has been attempted and another one is yet to be attempted, or the ball has gone out of bounds. Player substitutions may then be made.
The acceleration will be slower
Law of inertia
F=Ma 2 times slower
Answer:
Stayed the same
Explanation:
Potential energy is a function of mass, gravity and height relative to a reference level. If we take as the reference level the soil, this is the level where the potential energy is zero. Since in problem it is mentioned that the track is flat, this means that there are no height changes with respect to the reference level, therefore we can say that the potential energy remains unchanged.
Ep = m*g*h
where:
m = mass [kg]
g = gravity [m/s^2]
h = elevation [m]
