Answer:
49 m/s
Step-by-step explanation:
Given :
Time, t = 5 seconds
The vice falls from rest, therefore the initial velocity, u = 0.
We know acceleration due to gravity, g = 9.8 m/s2
Therefore, from equation of motion , we get
v = u + g.t
= 0 + (9.8 x 5)
= 49 m/s
Therefore the speed of the vice is 49 m/s after 5 second.
