Question

the brakes applied to a bus produce an acceleration of 4 m/s² in the opposite direction to the motion. If the bus takes 3 seconds to stop after the application of brakes, calculate the distance it travels during this time​

Answer 1

Answer:

1.5 metres

Explanation:

Given: a(acceleration)= 4m/s²

v(final velocity)= 0( as the bus stops)

t(time)= 3seconds

s(distance)= ?

Solution: we will have to find u i.e initial velocity

therefore, using v= u+ at

u= v-at

u= 0- 12

u= -12m/s

v²= u²+2as

v²-u²/2a= s

12/8= s

s= 12/8= 1.5metres
