Question

if a car at rest accelerates uniformly to a speed of 144km\h in 20sec then it covers a distance of​

Answer 1

Answer:

0.4km

Explanation:

u=0

v=144km/h=40m/s

v=u+at

40=0+a(20)

a=2m/s²

now x=ut+1/2at²

x=0+1/2(2)(20)²

x=400m

x=0.4km

Answer 2

Answer:

W=d/t

Explanation:

144=d/20

144×20=d

2880=d
