Question

A Ferrari starts moving from rest with 4 m/s square acceleration for 6 seconds and then with uniform velocity it keeps moving. After 10 seconds, a Lamborghini starts moving from same place with same acceleration.
Will they will meet more than once - Analyse mathematically

Answer 1

Answer:

Yes they Meet at a Point

Explanation:

t = 6 sec t = 10

a = 4m/s²

u =0m/s

v = ?

v = u + at

v = 0 + 4 x 6

v = 24m/s

S = v² - u²/ 2a

S = (24)² - (0)²/ 2 x 4

S = 576/8

S = 72 m

Speed. = S/t

= 72/6

= 12m/s

v = u + at

v = 0 + 4 x 10

v = 40m/s

S = v² - u²/ 2a

S = (40)² - (0)²/ 2 x 4

S = 1600/8

S = 200m

Speed. = S/t

= 200/10

= 20m/s

a.v Speed = 12/6

= 2m/s

a.v Speed = 20/10

= 2m/s

Yes they Meet at a Point
