Question

A bicycle increases its velocity from 10km/hr to 15km/hr in 6sec calculate its acceleration

Answer 1

Answer:

Explanation:

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

Answer: a=25/108 m/s^2

Explanation:a=v-u/t

here v=15km/hr which is equal to 15 x 5/18 m/s=75/18 m/s

       u=10km/hr= 10x5/18 m/s=50/18m/s

  a=v-u/t

v-u=75/18-50/18   =    25 /18m/s  

a= 25/18/t

t= 6s

a= 25/18/6

  =25/108 m/s^2
