Answer:
Explanation:
From work energy theorem
Work done by all forces = Change in kinetic energy
Lets take
m= mass of object
h=height from the ground surface
initial velocity of object = 0 m/s
The final velocity of object is v
Work done by gravitational force = m g . h
The final kinetic energy = 1/2 m v²
So
Work done by all forces = Change in kinetic energy
m g h = 1/2 m v² - 0
v² = 2 g h
Answer:
0.37 m
Explanation:
Given :
Window height, = 1.27 m
The flowerpot falls 0.84 m off the window height, i.e.
= (1.27 x 0.84 ) m in a time span of
seconds.
Assuming that the speed of the pot just above the window is v then,
m/s
Initially the pot was dropped from rest. So, u = 0.
If it has fallen from a height of h above the window then,
h = 0.37 m
