The ball has just left the tennis player's hand at a speed of 5.0 m/s The tennis ball has a mass of 0.058 kg
Write down the equation that links kinetic energy, mass and speed.

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Will you chech and finish these for me, because i am stumped with them.

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.
