(1) A car is traveling at a constant speed of 5 m/s. If the snow is falling at 4.1 m/s with an angle of 36 degrees to the vertical line toward the windshield, determine the velocity of the snow as seen by the driver.

Provide your answer in m/s. Round to the nearest two decimal places.

(2) A golfer hits a ball, giving it a maximum height of 12 m. If the ball lands 126 m away at the level from which he hit it, how long does it take for the ball to reach maximum height. (Neglect air resistance.)

Provide your answer in s and round to the nearest two decimal places.

(3) A golfer hits a ball, giving it a maximum height of 23 m. If the ball lands 139 m away at the level from which he hit it, what was its initial velocity in the horizontal direction (Neglect air resistance.)

Provide answer in m/s and round to the nearest one decimal place.

(4) If the golf ball has horizontal velocity of 0.0 m/s and vertical velocity of 0.8 m/s, what is the golf ball's resultant velocity?

Provide answer in m/s and round to the nearest one decimal place.

(5) Pulleys C and D in Figure are fastened together. Weights A and B are supported by ropes wound around the pulleys as shown. The radius for pulley C is 172 mm and the radius for pulley D is 126 mm.

If weight A is accelerating downward at 8.2 m/s², determine the angular acceleration of pulleys C and D.

Provide your answer in rad/s² and round to the nearest one decimal place.
