Question

A car starting from rest attains a velocity of 100 m/s in 10 s . Find the initial velocity, acceleration and distance covered by the car in that time

Answer 1

Step-by-step explanation:

Intial velocity=0

Acceleration=velocity/time

Acceleration=100/10

10m/s²

Distance=velocity×time

Distance=100m/s×10s

1000m

1km

Answer 2

Answer:

a = 4 m /s²

Explanation:

⇒ u = 0 m/s

⇒ v = 20 m/s

⇒ t = 5sec

⇒ a = ?

Equation used :

⇒ v = u + at

⇒ 20 = 0 + a × 5

⇒ 20/5 = a

⇒ 4 m/s² = a
