If you drop a silver dollar off a building and it hits the ground in 10 seconds, how fast was the coin going just before it hit?



Answer :

objects in free fall, disregarding terminal velocity, accelerate at 9.8(m/s)/s. so for every second it was falling, it gained 9.8m/s in speed. 9.8 * 10 = 98m/s

velocity = 9.8 x 10
velocity is 98 meters/second
Velocity is speed
