A pug is tossed up into the air. The pug has a mass of 10kg (it's a hefty pug). The pug reaches a maximum height and then falls back gently into the owner's loving arms. **NO PUGS WERE HARMED IN THE WRITING OF THIS QUESTION** a) What is true about the pug's velocity at the maximum height? Why? b) How long will it take for the pug to go up and down if the pug's initial velocity is 10 m/s upwards? c) With what minimum force will the pug need to be thrown with to reach a maximum height of 2m? **part (c) should be left in variable form as not enough information is given for a numerical answer!**
