An airplane propeller is 2.68 m in length (from tip to tip) and has a mass of 117 kg. When the airplane's engine is first started, it applies a constant net torque of 1990 N·m to the propeller, which starts from rest. . What is the angular acceleration of the propeller? Model the propeller as a slender rod. Express your answer in radians per second squared. View Available Hint(s) a = 28.4 rad/s Submit Previous Answers Correct What is the propeller's angular speed after making 5.00 revolutions? Express your answer in radians per second. How much work is done by the engine during the first 5.00 revolutions? Express your answer with the appropriate units. What is the average power output of the engine during the first 5.00 revolutions? Express your answer with the appropriate units. What is the instantaneous power output of the motor at the instant that the propeller has turned through 5.00 revolutions? Express your answer with the appropriate units.

A projectile is launched with an initial speed of 43.0 m/s at an angle of 35.0° above the horizontal. The projectile lands on a hillside 3.90 s later. Neglect air friction. (Assume that the +x-axis is to the right and the +y-axis is up along the page. (30 points) a) What is the projectile's velocity at the highest point of its trajectory? (You must find the magnitude and direction of the velocity). Magnitude: (10 points) Direction: (10 points)
