A tired squirrel (1kg mass) does push-ups by applying a force to elevate its chest by 5 cm. Estimate the number of push-ups that a tired squirrel must do in order to do approximately 5J of work.

You are given two vectors a⃗ =−3.00ι^ 5.00j^ and b⃗ =5.00ι^ 2.00j^. let the counterclockwise angles be positive.
