Question

A bus starts from the stop and take 50seconds to get the speed of 10 metre per second. if the mass of the bus alongwith passenger is 10000 kg , then calculate the force applied by the engine of bus to push the bus at the speed of 10meter per second. ​

Answer 1

acceleration=m/s2=10/1×1=10

mass=10000

force =acceleration × mass=10×10000=100000

plz mark as the brain list answer.❤❤❤

Answer 2

Answer:

2000N is the right answer

You can see the Attachment For Solution or I am typing it here

As Acceleration =

Final velocity-Initial velocity/Time

So Acceleration =

$10 - 0 \div 50$

So acceleration =1/5 m/s^2

As force = Mass x Acceleration

Force = 10000 x 1/5

Force = 2000Newton

Thanks for Asking.
