Question

solve ..............plzzzz​

Answer 1

$\large\boxed{Answer}$

Here ,

u = 36 km/hr = 36 × 5/18 = 10 m/Second

v = 72 km/hr = 72 × 5/18 = 20 m/Second

a = (v - u)/t

= (20 - 10)/5

= 10/5

= 2 m/Sec²

Distance travelled by the car in 5 seconds-

S = ut + 1/2*at²

= 10 × 5 + 1/2 *(2)(5)²

= 50 + 25

= 75 meter

Answer 2

Here ,

u = 36 km/hr = 36 × 5/18 = 10 m/Second

v = 72 km/hr = 72 × 5/18 = 20 m/Second

a = (v - u)/t

= (20 - 10)/5

= 10/5

= 2 m/Sec²

Distance travelled by the car in 5 seconds-

S = ut + 1/2*at²

= 10 × 5 + 1/2 *(2)(5)²

= 50 + 25

= 75 meter
