Answer to Question #258096 in General Chemistry for taerah

Question

A coin is tossed from a height of 1.2 m from the ground. Assume that the coin follows a perfect vertical path with an initial velocity of 3.0 m/s.

a.How long should the coin travel to go back to its original position?

b.What is the velocity of the coin after 5.0 s?

c.What is its displacement after 0.52 s?

Answer 1

H=(V²-U²)

1.2= 3²-U²

1.2= 9-U²

1.2-9=-U²

-7.8=- U²

U= 2.79m
