Physics 20 acceleration due to gravity questions
An object is thrown downwards, hitting the ground with a velocity of 10m/s . it fell for 0.880seconds. At what velocity was the object released.

The object was released with a velocity of 17.8 m/s, given the formula v = g x t + v₀, where g is the acceleration due to gravity (9.8 m/s²), t is the time in seconds (0.880 s) and v₀ is the initial velocity (which is the velocity at which the object was released). So v = 9.8 x 0.880 + v₀, giving 17.8 m/s.
