Answer:
because energy will be lost due to friction, sound, and heat (arguably similar to friction) and ENERGY MUST STAY THE SAME so it is IMPOSSIBLE for the ball to bounce higher than when dropped!
You would do distance divided by speed. So 150÷3, which would equal 5km per hour.
Your question seems incomplete, however, I might help you solve the problem even though the values are not given. The intensity of a traveling plane electromagnetic wave can be computed using the following equation:
S = (c/u0) * B^2
where s is the EM wave intesity
c is the speed of light
B is the magnetic field
u0 is the energy density
Momentum is a vector quantity, and is always conserved. Whenever a collision occurs between two objects, the objects behave under the principle of conservation of momentum. Therefore, if an object moves in the direction opposite to its original direction after a collision, then this indicates that the momentum of the colliding object was greater than the object under consideration.
It will take them nine seconds to move 36 meters
