Question

A car increse its speed from 18km/h to 36km/h in 5seconds. Caluclate acceleration and distance covered

Answer 1

u = 18km/hr = 5m/s

v = 36km/hr = 10m/s

t = 5s

a = v-u/t

=> 10-5/5

=>5/5

=>1m/s²

s = ut+½at²

s = 5×5 +½×1×5²

s = 25+12.5

s = 37.5

So, the distance covered us 37.5m.

Cheers!
