Question

bicycle increases its velocity from 10 kilometre per hour to 15 km per hour in 6 seconds. calculate its acceleration.

pls​

Answer 1

Answer:

hey mate i am not able to write the formula that's why I am posting a pick of the formula for acceleration ok

Total velocity before increasing is 10km/hour=60m

Total velocity after increasing is = 15/60 .

final velocity = v1 and initial velocity =v2

Hey I have done this type of sum for the first time so plz check my ans one's ha . because I am still in 8th standard

hey mate I think my ans is wrong check for this one .

Initial velocity = u = 10 km /hr

= 10 x 5 /18

= 2.77777

= 2.8 m /s

Final velocity = v = 15 km / hr

= 15 x 5 / 18

= 4.16 m /s [ approx .]

Time = t = 6 sec

a = acceleration

Equation of motion :

v = u + at

4.16 = 2.8 + 6a

6a + 2.8 = 4.16

6a = 4.16 - 2.8

6a = 1.36

a = 1.36 / 6

a = 0.22 m /s.square
