4. A lizard kicks a ball with an initial velocity of 10 m/s at an angle of 35° with the horizontal. a. What are the horizontal and vertical components of the initial velocity? b. What is the total time the ball is in the air? c. What is the maximum height of the ball?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
