An object is accelerating is at the rate of ‘a1’ m/s2. If suddenly the net force exerted is doubled and the mass is quadrupled, find the new acceleration ‘a2’.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

On mars a rock falls an unknown vertical distance from a resting position and lands in a crater. if it takes the rock 2.5 seconds to fall, how high is the cliff the rock fell from? mars' surface gravity is 3.8 m/s2.
