A race car accelerates uniformly from a velocity of 21.5 m/s to 54.1 m/s in 2.47 s. Determine the acceleration of the car.
21.5 m/s
Please help me!
Thank you

Oxygen and hydrogen gas are at the same temperature t.what is the ratio of kinetic energies of oxygen molecule and hydrogen molecule if oxygen is 16 times heavier than hydrogen.

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.
