Question

a bus was moving at a rate of hundred metre per second when brakes are applied it comes to rest in a distance of hundred metre find retardation produced by bus​

Answer 1

Answer:

-50 m/s²

Explanation:

Given :

• Initial velocity = u = 100 m/s
• Final velocity = v = 0 m/s
• Distance travelled = s = 100 metres

To find :

• Retardation produced by the bus

Using the third equation of motion :

• V²-u²=2as

Substituting the values :

0²-100²=2×a×100

0-10000=200a

a = - 10000/200

a = - 50 m/s²

The acceleration produced by the bus is equal to - 50 m/s²

Answer 2

Answer:

Answer: -50m/s sqr.

Explanation:

u = 100m/s

v = 0m/s

a = ?

Using third equation :

2as = v sqr - u sqr

= 10000/2*100

= 50

a = - 50 m/s sqr.
