Youre carrying a 4.0-m-long 25 poles to a construction site, Ask an Expert

Academics

Q1. You're carrying a 4.0-m-long, 25 poles to a construction site when you choose to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35 from its tip. How much force should you exert to keep pole motionless in a horizontal position?

Q2. A player passes a 0.800- basketball down court for a fast break. The ball leaves the player's hands with a speed of 7.30 and slows down to 7.00 at its highest point. Ignoring air resistance, how high above the release point is the ball while it is at its maximum height?
