Question

A bus increases its speed from 8km/h to 60km/h in 5s. find acceleration of the bus.

Answer 1

Answer:

a = 2.334 m/$s^{2}$

Explanation:

Heya friend,

We know,

By 1st equation of motion :-

v = u + at,

Here,

v = 60 km/hr

  = 60 × $(\frac{5}{18} )$ m/s

  = 16.67 m/s

and,

u = 8 km/hr

  = 8 × $(\frac{5}{18} )$ m/s

  = 5 m/s

So,

16.67 = 5 + a(5)

5a = 11.67

a = $\frac{11.67}{5}$ m/$s^{2}$

a = 2.334 m/$s^{2}$
