An Object is thrown straight up into the air with an initial velocity of 15m/s. What is its velocity at the peak of its flight?

0

Explanation:

The initial velocity of an object is 15 m/s when it was thrown straight up into the air.

At maximum height, the velocity of the object is equal to 0. It starts coming  downward after that and falls ground. Height attained by the object is given by :

Hence,  its velocity at the peak of its flight is equal to 0.

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
