Question

A big cruise ship dropped anchor off the Caribbean island of Barbuda. The heavy anchor was released from a height of

54
5454 meters above the water's surface, and it fell at a constant rate. After
35
3535 seconds, the anchor was
9
99 meters below the water's surface.
How fast did the anchor drop?
meters per second
How long did it take the anchor to reach the water's surface?
seconds

Answer 1

54+9= 63 m = distance and time=35 sec hence, speed= 63/35=9/5=1.8 m/s

time taken to reach water surface= distance/speed=54/1.8=30 sec
