Question

Answer these two questions as soon as possible ​

Answer 1

Answer:

u = 0

v = 144 km/h = 144 × 5/18 = 40 m/s

t = 20s

By using 1st equation of motion:

v = u + at

40 = 0 + a (20)

40 = 20a

a = 40/20

a = 2 m/s²

By using 2nd equation of motion :

s = ut + 1/2 at²

s = 0 × 20 + 1/2 × 2 × 20 ×20

s = 400 m

Answer 2

ans is 400m
