Answer :
The mass of the bus that accelerates from 10m/s to 15 m/s is 600 kg.
What is mass?
Mass is the quantity of matter a body contains.
To calculate the mass of the bus, we use the formula below.
Formula:
- m = Ft/(v-u)................... Equation 1
Where:
- m = Mass of the bus
- t = Time
- F = Force
- v = Final velocity
- u = Initial velocity
From the question,
Given:
- F = 3000 N
- t = 10 seconds
- v = 15 m/s
- u = 10 m/s
Substitute these values into equation 1
- m = (3000×10)/(15-10)
- m = 30000/5
- m = 6000 kg
Hence, the mass of the bus is 600 kg.
