Answer:
<h2>65 kg</h2>
Explanation:
The mass of the person can be found by using the formula
p is the momentum
v is the velocity
From the question we have
We have the final answer as
<h3>65 kg</h3>
Hope this helps you
Answer:222 meters
Explanation:
Speed=80kph=(80x5/18)=(80x5)/18=22.2m/s
Time=10 seconds
distance=speed x time
distance=22.2 x 10
distance=222
distance=222 meters
The distance between the resting point and maximum height of the wave is 0.2 cm.
The amplitude is measured from the resting point up to the highest point of the wave.
Some people just know it. Do you have a question?
Answer:
The work done is, w = 6 x 10² J
Explanation:
Given,
The angle of the incline, ∅ = 30°
The force applied parallel to the incline, F = 60 N
The displacement caused by the force along the incline, s = 10 m
Since the force and displacement is along the incline, the angle of incline doesn't contribute to the work done.
The work done by the force is given by the relation,
W = F · S
= 60 N x 10 m
= 600 J
Hence, the work done by Roger pushing the box is, W = 600 J
