A car starts from rest and attains a velocity of 20m/s in 5s. Calculate the distance during thistime.​

Answer»

Answer:

50 m

Explanation:

  • GIVEN : u = 0 m/s
  • : v = 20 m/s
  • : T = 5 s
  • To FIND : S = ?
  • We know that
  • a = v - u/ t
  • a = 20 - 0 / 5
  • a = 4 m/

Now

By 2 equation of motion

S = ut + 1/2 at²

S = 0 × 5 + 1/2 × 4 × 5²

S = 0 + 1/2 × 4 × 25

S = 1 × 2 × 25

S = 50 m

Hope It helps you

Thanks
