Question

A racing car has of 2 cm/s2 what will be its velocity 3 seconds after the start.
plz tell me thank u​

Answer 1

Answer:

v= u+at

u= 0

v= at

v= 2*3

v= 6cm/sec

Answer 2

Answer:

Given that

Initial velocity (u) = 0 ( as the racing car begins from the rest position)

Acceleration (a) = 0.02 ms-2

Time (t) = 3s

Find out

velocity 3 s after the start

Formula

As per the first motion equation, v = u + at

Therefore, terminal velocity of the car

(v) = 0 + (0.02 ms-2)(3s)

= 0.06 ms-1

Therefore, the velocity of the racing car after 3 seconds will be 6 cm.s-1
