A golfer hits a golf ball on a flat, horizontal surface with an initial velocity of 67.7 m/s @ 45°.

Cedar has been trying to get Liam's attention for weeks.  He decides to make a paper airplane to hit Liam in the back of his head (and grab his attention).  If the paper airplane flies 2.64 m [W 26˚ N] and then is caught by the wind, which causes it to travel 3.21 m [S 12˚ E].  What is the paper airplane's total displacement?   (please hand-write it and make it clear)

9. If a projectile (such as a bullet) is fired into the air with an initial velocity v at an angle of elevation of θ (see the figure), then the height h of the projectile at time t is given by

a) the place where the rock lands.  b) the velocity of the rock (magnitude and direction) just before it lands.

Professional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. c) Find the average force exerted by the club on the ball. d) Find the average shear deformation of the club's 0.800 m long and 1.00 cm diameter steel shaft.

6. A bullet traveling horizontally at a speed of 395 m/s hits a board perpendicular to the surface, passes through it, and emerges on the other side at a speed of 175 m/s. If the board is 3.30 cm thick, how long does the bullet take to pass through it? 0 ssY 60 s ssf60 ssf6 60 ssf60 s

A carnival game has you throw a ball through a hoop as the hoop falls from some height. 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.

Doha kicks the ball in a parabolic path. The ball leaves the player’s foot with a speed of 20 m/s, making an angle of 40 o with the horizontal. a) Calculate the maximum height of its trajectory  b) Determine its velocity as it hits the ground again. Air resistance is negligible. c) How far from Darshan does the soccer ball land?

A catfish is spotted at the bottom of a creek. The depth of the water is 2 m. A hunter (with no knowledge ofoptics) fires a rifle shot, directly aimed at the catfish. The bullet strikes the water at an angle of 40° to the water. Assumethat the bullet is not deflected by the air/water interface, what is the distance from the bullet hole at the bottom of the creekto the catfish?A) 0.88 mB) 0.97 mC) 0.49 mD) 0.56 mE) 0.73 m
