When a car of mass 1167 kg accelerates from 10.0 m/s to some final speed, 4.00 × 105 j of work are done. find this final speed?

final speed = 28 m/s

Explanation:

As per work energy theorem we know that

Work done on the object = change in kinetic energy

so here we have

now we will have

also we know that

mass = 1167 kg

and initial speed is given as

now from above work energy equation we will have

unbalanced force
