Question

a racing car has a uniform acceration of 4 m/s what will distance will cover in 105 after the starts?​

Answer 1

Answer:

Correct Question ➪

A racing car has a uniform acceleration of 4m/s² . What distance will it cover in 10s after it starts ?

Correct Answer ➪

acceleration (a) = 4m/s²

time (t) = 10s

initial velocity (u) = 0m/s

distance (s) = ?

By using equation of motion →

⇒ s = ut + ½ at²

⇒ s = 0(10) + ½ (4)(10)(10)

⇒ s = 0 + 2(100)

⇒ s = 200m

hey mate! Time t = 10 sec. Velocity v after 10 sec= u + a t = 0 m/s + 4 m/s² × 10 s =40 m/s.
