Question

Initial speed50km/h final velocity 100k/h accelarates 1m /s^2 time taken for this

Answer 1

Answer:

initial speed = 50km/h -----------------> 13.88m/s

final = 100km/h-------------------------> 27.77m/s

acc = 1m/s^2

v = u + at

27.77 = 13 .88 +1t

13.89s= t

Answer 2

Answer:

ans

Explanation:

u=50×5/18 m/s

v=100×5/18 m/s

a=1m/s^2

t=?

put these value in 1st eqation of motion

v=u+at

100×5/18=50×5/18+1×t

500/18=250/18+1×t

27.77=13.88+1×t

27.77=14.88×t

t=27.77/14.88

t=1.8662 seconds
