Question

A 5 kg book falls from a shelf. If it lands at a speed of 5.7 m/s, from what height did it fall?

Answer 1

Answer:

57m

Explanation:

speed = 5.7m/s

or 57/10 m/s

so definitely the time taken will be 10 secs

so speed = distance/time taken

5.7= distance/10

distance = 5.7× 10

Distance = 57m
