Question

A bus travelling at a speed of 54 km/h speeds up to 72 km/h in 5 seconds. Calculate the acceleration of the bus.

Answer 1

Answer:3.6 m/s^2

U=54 km/h

V=72 km/h

t=5 s

$a = v -u \div t$

$a = 72-54\div 5$

$a = 18 \div 5$

$a = 3.6$

Acceleration of the bus=3.6 m/s^2

Information about Acceleration

Acceleration is the rate of changing of velocity

a=v-u/t

SI unit=m/s^2

Acceleration having negative value known as Retardation or Deccelartion

Acceleration is a vectar quantity
