An object undergoes a constant acceleration of 8 m/s2 starting from rest. Find the distance travelled by the object in one second.

A car falls off a ledge and drops to the ground in 0.8 s. Taking g = 10 m/s2, how high is the ledge from the ground?

If a ball is thrown vertically upward with an initial speed of 3 m/s, find the maximum height it will reach. (Take g = 10 m/s2)
