Answer:
they are happy cause he jumped off a bridge
Explanation:
The answer c for your question
To determine the distance that you would travel by.
Simply convert 15 minutes to seconds which would be 900 seconds.
Then solve for distance, which would be
D = r • t
D = 12 m/s • 900 s
D =10 800 m.
This is the distance that you had ran for.
The speed of the vehicle after the push is 2.7 m/s.
<h3>What is velocity?</h3>
velocity is the rate of change of displacement.
To calculate the velocity of the vehicle, we use the formula below.
Formula:
- v = √[2(W-W')/m]............... Equation 1
Where:
- W = work done by the pusher
- W' = Work done by friction
- m = mass of the car
From the question,
Given:
- W = 6500 J
- W' = 2000 J
- m = 1200 kg
Substitute these values into equation 1
- v = √[2(6500-2000)/1200]
- v = √(7.5)
- v = 2.7 m/s
Hence, the speed of the vehicle after the push is 2.7 m/s.
