Question

A mechanic pushes a 3540 kg car from rest to a speed of v, doing 4864 J of work in the process. Find the speed v. Neglect friction between car and road. Answer in units of m/s.

Answer 1

1.66 m/s

Step-by-step explanation:

Work or kinetic energy =
`(1)/(2) mv^(2)`

`4864=(1)/(2) (3540)v^(2)`

v = 1.66 m/s
