Question

A car traveling with a velocity of 24 m/s is accelerated uniformly at 1.6 m/s 2 for 6.8 s. What is its final velocity? Answer in units of m/s

Answer 1

`"34.9 m/s"`

Explanation:

`v = u + at`

Where

• `v` = Final velocity
• `u` = Initial velocity
• `a` = Acceleration
• `t` = Time taken to change its velocity from `u` to `v`

Substitute the given values in above equation of motion

`v = "24 m/s" + ("1.6 m/s"^2 × "6.8 s") = "34.9 m/s"`
