A 16.0-kg cannonball is fired from a cannon with muzzle speed of 900 m/s at an angle of 32.0∘ with the horizontal. A second ball is fired with the same initial speed at an angle of 90.0∘. Let y = 0 at the cannon. (a) Use the isolated system model to find the maximum height reached by each ball. hfirst ball = mhsecond ball = m (b) Use the isolated system model to find the total mechanical energy of the ball-Earth system at the maximum height for each ball. Efirst ball Esecond ball = J

Use the model for projectile motion, assuming there is no air resistance and g = 32 feet per second per second. The quarterback of a football team releases a pass at a height of 6 feet above the playing field, and the football is caught by a receiver 40 yards directly downfield at a height of 4 feet. The pass is released at an angle of 35∘ with the horizontal. (a) Find the speed (in ft/sec) of the football when it is released. (Round your answer to three decimal places.) ft/sec (b) Find the maximum height (in ft) of the football. (Round your answer to one decimal place.) ft (c) Find the time (in sec) the receiver has to reach the proper position after the quarterback releases the football. (Round your answer to one decimal place.) sec
