A 30.0kg object has an initial velocity of 7.00m/s and a final velocity of 10.0m/s. The work done on the object is

Answer 1

135

Step-by-step explanation:

m=30kg

initial speed=7.00

final speed=10.0

`ke = (1)/(2) m(v - v) {}^(2)`

1. 
   `ke = (1)/(2) * 30(10- 7) {}^(2)`

Answer 2

I think the answer is 60
