Air resistance doesn't appear in the formula for gravitational force, because it doesn't affect it. Mass does because it does.
The formula of the kinetic energy is:
where m is a mass of the object, v is speed of the object at the moment of time. So we have:
The answer is
2000 Joules.
A. when it reaches the top of its flight
potential energy increases as the height of the object does, and the highest point of a ball's flight is when it reaches the top.
The period of the pendulum is the reciprocal of the frequency:
The period of the pendulum is given by
where L is the length of the pendulum, and g the acceleration of gravity. By re-arranging the formula and using the value of T we found before, we can calculate the length of the pendulum L:
Answer:
They sh0uld g0 t0 the reactor and then, see what the issue is...
Explanation:
then, see if they can fix the problem, im sorry if its wr0ng.
