Birds of prey typically rise upward on thermals. The paths these birds take may be spiral-like. You can model the spiral motion as uniform circular motion combined with a constant upward velocity. Assume the a bird completes a circle of radius 6.00 m every 5.00 s and rises vertically at a constant rate of 3.00 m/s. Determine the bird's direction of acceleration in degrees above the horizontal.
The maximum horizontal distance a boy can throw a ball is 50 m. Assume he can throw with the same initial speed at all angles. How high does he throw the ball when he throws it straight upward?

- Just before a field goal kick attempt at a football game, you use your knowledge of kinematics to predict by how much the football will clear the horizontal crossbar which is 3m from the ground. From the location of the football, you know the distance of the kick to be 35m. Assuming you estimate the angle of the kick is 45 degrees, and the initial speed is 20 m/s, determine the height of the ball at the location of the goal post.arrow_forwardAn electron moves with a constant horizontal velocity of 3.0*10^6 m/s and no initial vertical velocity as it enters a deflector inside a TV tube.
