1.A golfer hits a shot to a green that is elevated 2.80 m abovethe point where the ball is struck. The ball leaves the club at aspeed of 19.9 m/s at an angle of 32.0Ëš above the horizontal. Itrises to its maximum height and then falls down to the green.Ignoring air resistance, find the speed of the ball just before itlands.
2.A 53.8-kg crate rests on a level floor at a shipping dock. Thecoefficients of static and kinetic friction are 0.720 and 0.379,respectively. What horizontal pushing force is required to(a) just start the crate moving and(b) slide the crate across the dock at a constantspeed?
PLZ help me with these two Questions. Thanks a lot.
