A bus is moving at a speed of 20 m/s, when it begins to slow at a constant rate of 5 m/s2 in order to stop at a bus stop. If it comes to rest at the bus stop, how far away was the bus from the stop?

Respuesta :

Answer:

u=20m/sec

v=0

a=5m/sec^2

v^2=u^2-2as[ here acceleration is negative]

0=400-2x5xs

-400= -10s

s= 40 metre.
