Question

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

Answer 1

v is final velocity
u is initial velocity
t is time
a is acceleration
u=10 km/h
v=15km/h
t=6 seconds
convert velocity in m/s
u=10000m/sec
v=15000m/sec
t=6 seconds
a=v-u /t
5000/6
so ,acceleration is=
833.33 m/sec ^2

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
