A truck heading east has an initial velocity of 6 m/s. It accelerates at 2 m/s for 12 second's. what's distance does the truck travel in the given time

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s

What ia the energy of an object because of its potential and kinetic energies
