Question

(iv) A car accelerates uniform from 18km/h to 36km/h in 2 seconds. Calculate<br />the distance covered by the car in that time.​

Answer 1

Answer:

16 is correct answer my mind

Answer 2

Answer:

15m

Step-by-step explanation:

u=18km/hr=18×5/18 m/s=5m/s

v=36km/hr=36×5/18=10m/s

now t=2 sec.

s=?

from eq of motion

v=u+at

10=5+2a

a=5/2

a=2.5m/s²

now s=ut+1/2at²

s=5×2+1/2×2.5×4

s=10+5

s=15m

so distantce coverd by car in 2sec. is 15m
