Question

Find the acceleration of a car which increases its speed from 20 m/s to 50 m/s in 5 seconds.
Find the initial velocity of a car whil​

Answer 1

Answer:

we know

v=u+ft

here v=final velocity=50m/s

u =initial velocity=20m/s

t=time=5sec

f=acceleration=?

so,

50=20+f.5

5f=50-20

=> 5f=30

=> f=30/5

=> f=6

so acceleration = 6 m/sec^2
