Question

bus of mass 1200kg is moving along a straight path with a uniform

velocity of 80Km/h. Its velocity decreases to 40 Km/h due to an (3)

unbalanced force on the bus in 5s. Find​

Answer 1

Answer:

I cant understand that

Answer 2

Step-by-step explanation:

acceleration of bus=40-80/5= -8km/h²

= -20/9m/s²

force= mass×acceleration

=1200× -20/9= 2666.67newton
