For problems 3,4, and 5, Consider an egg that has a mass of 0.15 kg being held at the top of a flight of stairs. 3. If an egg has 11 J at the top of the stairs, what is the height of the stairs?

4. If the egg is dropped from that height, what is the Kinetic energy right before the egg hits the ground?

5. If the egg is dropped down to the ground from that height, what is the velocity of the egg right before the egg hits the ground?

My answer is opptionc, just check with anyone else

It may possibly be c i think |-/

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
