The vertical distance as the object was raised is 40 m.
<h3>What is vertical distance?</h3>
This is the distance between two vertical positions in space. Vertical distance can also be called height.
To calculate the vertical distance at which the object was raised, we use the formula below.
Formula:
- P = Fd/t.................... Equation 1
Where:
- P = Power of the motor
- F = Force
- d = vertical distance
- t = time.
Make d the subject of the equation.
- d = Pt/F............. Equation 2
From the question,
Given:
- P = 120 watt
- F = 15 Newton
- t = 5.0 seconds
Substitute these values into equation 2
Hence, the vertical distance as the object was raised is 40 m.

This year is 60 years since I learned this stuff, and one of the things I always remembered is the formula for the distance a dropped object falls:
D = 1/2 A T²
Distance = (1/2) (acceleration) (time²)
The reason I never forgot it is because it's SO useful SO often. You really should memorize it. And don't bury it too deep in your toolbox ... you'll be needing it again very soon. (In fact, if you had learned it the first time you saw it, you could have solved this problem on your own today.)
The problem doesn't tell us what planet this is happening on, so let's make it easy and just assume it's on Earth. Then the 'acceleration' is Earth gravity, and that's 9.8 m/s² .
In 5 seconds:
D = 1/2 A T²
D = (1/2) (9.8 m/s²) (5 sec)²
D = (4.9 m/s²) (25 sec²)
D = 122.5 meters
In 6 seconds:
D = 1/2 A T²
D = (1/2) (9.8 m/s²) (6 sec)²
D = (4.9 m/s²) (36 sec²)
D = 176 meters
There is a basic difference<span>, because </span>mass<span> is the actual amount of material contained in a body and is </span>measured<span>in kg, gm, etc. Whereas </span>weight<span> is the force exerted by the gravity on that object mg. Note that </span>mass<span> is independent of everything but </span>weight<span> is different on the earth</span>
Answer:
A. Its translational kinetic energy is larger than its rotational kinetic energy.
Explanation:
Given that
Radius = R
Mass = M
We know that mass moment of inertia for the solid sphere
Lets take angular speed =ω
Linear speed =V
Condition for pure rolling , V= ω R
Rotation energy ,RE
RE= 0.2 MV²
The transnational kinetic energy TE
TE= 0.5 MV²
From above we can say that transnational energy is more than rotational energy.
Therefore the answer is A.
