- A projectile is launched at a height of 20 m at an angle of 40 degrees, with what speed must it leave so that it achieves a range of 100 m? g=9.8m/sA 0.54-kg ball is thrown vertically upward with an initial speed of 14.0 m/s. What is the speed of the ball when it hastravelled three-quarters of the distance to its maximum height?3.On level ground a shell is fired with an initial velocity of40.0 m/s at 60.0° above the horizontal and feels no appreciable air resistance.(a) Find the horizontal and vertical components of the shell’s initial velocity. (b) How long does it take the shell to reach its highest point? (c) Find its maximum height above the ground. (d) How far from its firing point does the shell land? (e) At its highest point, find the horizontal and vertical components of its acceleration and velocity.
- A projectile is thrown horizontally at 14.0 m/S. The projectile hits the ground 0,510s later. What is the angle of impact the projectile makes with the horizontal ground?A golfer hits a shot to a green that is elevated 3.30 m above the point where the ball is struck. The ball leaves the club at a speed of 18.4 m/s at an angle of 45.0˚ above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands.A cannon on top of a 55m high embattlement fires horizontally at 250 m/s. Where does the cannonball land? g =10 m/s^2 h=55
- A projectile is thrown from the top of a cliff with an initial speed of 25 m/s at an angle of 600 up from the horizontal. If the projectile lands 100 m from the base of the cliff how tall is the cliff?Before jumping from the bridge, Martin throws his water bottle to a friend standing on the bank of the lake. The bridge is 7.0 m high. The friend is standing on the bank 15.0 m from the base of the bridge with their hand 1.0m above the ground. What speed must Martin throw the bottle horizontally for it to reach his friend's hand?3. A baseball is hit for a homerun. It leaves the bat at an angle of 60° with a speed 70m/s and travels into the second level of the outfield seats which is 180m horizontally and 60m vertically away from and above home plate. How fast is the ball moving when the fan catches it? Neglect friction.

Suppose for onesuch game the hoop falls from a height of 2.0 m above your hand when you throw the ball, and you stand ahorizontal distance of 3.0 m away. If you throw the ball right when the hoop is released (from rest), at whatangle must you throw the ball in order for you to win the prize?8. You fire a ball with an initial speed of v at an angle o above the surface of an incline, which is itself inclined at an angle e above the horizontal. a) Find the distance, measured along the incline, from the launch point to the point when the ball strikes the incline. b) What angle o gives the maximum range, measured along the incline? Ignore air resistance.
