1.

a bus starting from rest moves with a uniform acceleration of 0.1 metre second -2 for 2 minutes find the speed acquired distance travelled

Answer»

Here is your answers -:




•Acceleration 'a' = 2m/s²

•Time 't' = 2 minutes = 120 seconds

The bus STARTED from rest.

•So, INITIAL velocity 'u' = 0




To FIND -

Final velocity 'v' = ?

Distance travelled 's' = ?

_____________________________


a \: = \: \frac{v - u}{t}

v \: = \: u + at
v \: = \: 0 + 2 \times 120
v = 240

Thus, v = 240m/s

___________________________



s \: = \: ut \: + \: \frac{1}{2} a {t}^{2}
s \: = \: 0 \times 120 \: + \frac{1}{2} \: \times 2 \times {120 }^{2} \\ s = {120}^{2} \\ s = 14400 \: metre

Thus,.



s = 14400m or 14.4km
