Question

A car is accelerating from rest at a rate of 2 (m/s)/ s. How fast will it be going after 4 seconds?​

Answer 1

8 m/s

Step-by-step explanation:

The Formula

• v = u + at

⇒ v = final velocity

⇒ u = initial velocity

⇒ a = acceleration

⇒ t = time taken

Given

• u = 0 [rest]
• a = 2 m/s
• t = 4 s

Solving

• v = u + at
• v = 0 + 2(4)
• v = 8 m/s
