You drop an object from rest (initial velocity = 0) from a height of 6.8 metres. What is the final speed of the object as it hits the floor? (Speed is a magnitude and so must be a positive value). Assume the magnitude of the acceleration due to gravity g = 9.8 m/s2. Give your answer to 2 s.f.
A racing enthusiast claims that his sports car will accelerate from rest to a speed of 43.0 m/s in 8.10 s.
