Q1. Setting a world record in a 100m race, Maggie and Judy cross the finish line in a dead heat, both taking 10.0 s. Accelerating uniformly, Maggie took 2.0 s and Judy 2.5 s to attain maximum speed that they maintained for the rest of race.

Q2. An arrow is fired horizontally with speed of 89 m/s directly at the bull's eye of a target 60 m away. When it is fired, the arrow is 1 m above the ground. How far short of the target does it strike the ground?
