Question

A bicycle increasas its speed from 10km/h to 15km/h in 6 seconds.Calculate its acceleration

Answer 1

15-10=5,5÷6=0.833333333

Answer 2

Hi friend,

Question : A bicycle increases its velocity from 10km/h to 15km/h in 6 seconds. Calculate its acceleration.

Answer : Final Velocity (v) = 15km/hr

Initial Velocity (u) = 10km/hr

Time = 6 seconds

Acceleration = ?

According to Formula :

Acceleration = v – u / t

Acceleration = 15km – 10km / 6 seconds

Acceleration = 15000m – 10000m / 6 seconds

[we will convert smaller units into bigger units. because in time we have smaller unit and here we cant convert time in hours or minute because it is only 6.]

Acceleration = 5000m / 6 seconds

[ means that we will divide 5000 by 6 . You acn also use cancellation method]

Acceleration = 833.333333
