Answer:
W = 0
Explanation:
We are given with, a construction worker is carrying a load of 40 kg over his head and is walking at a constant velocity. He travels a distance of 50 m.
The work done by an object is given by :
F = ma
So,
m is mass
a is acceleration
d is displacement
The worker is moving with constant velocity, its acceleration will be 0. So, the work done by the worker is 0.

Answer:
270 Kg e 130 kg
Explanation:
how many times is the number put together
Answer:11.101 m/s
Explanation:
Given
Velocity of eagle=3.1 m/s
Eagle is at height of 5.8 m
Fish is dropped with a horizontal velocity of 3.1 m/s
time taken by fish to reach lake is
here u=0 (vertical velocity)
t=1.087 s
Vertical velocity acquired by fish is v=u+at
Horizontal velocity=3.1 m/s
Therefore net velocity
below horizontal
