In the Superbowl, a quarterback throws a football while standing at the very center of the field on the 50 yard line. The ball leaves his hand at a height of 5 ft and has initial velocity of ~v(0) =< 40, 35, 32 > ft/sec. Assume an acceleration of 32 ft/sec2 due to gravity, i.e., ~a(t) =< 0, 0, −32 >, and that the vector ~i points down fieldtoward the endzone and that the vector ~j points to the sideline. The field is 150 ft in width and 300 ft in length.(a) Determine the position function that gives the position of the ball t seconds after it isthrown. (b) The ball is caught by a player 5 ft above the ground. Is the player in bounds or out ofbounds when he receives the ball? (Assume the player is standing vertically with bothtoes on the ground at the time of reception.)
A batter hits a fly ball which leaves the bat 0.90 m above the ground at an angle of 61° with an initial speed of 28m/s heading toward centerfield. Ignore air resistance.(a) How far from home plate would the ball land if notcaught? (b) The ball is caught by the centerfielder who,starting at a distance of 105 m from home plate just as the ballwas hit, runs straight toward home plate at a constant speedand makes the catch at ground level. Find his speed.
