John throws a football from the 50 yard line to the end zone. John throws with an initial velocity of 25.2m/s (56 mph) at an angle of 67.3 above the horizontal. At this velocity and launch angle, the football goes a horizontal distance of 46.1 meters and reaches a maximum height of 55.9 meters. How long is the football in the air for? Please show steps and equations used.
Homework Answers
Here, time taken = 2*u*sin(theta)/g
= 2 * 25.2 * sin(67.3)/9.8
= 4.74 sec -------------------> long is the football in the air for

2. A baseball thrown from the outfield, a golf ball, or a thrown football, all will follow a trajectory (path) that has horizontal as well as vertical displacement components. If we neglect the air friction on the ball, the path will be a perfect parabolic trajectory. The equations for the displacement of the ball are: Take gravity g as 9.81 meters per second, and the initial velocity, Vo, equal to 35 meters/second. Use Excel to show the ball trajectory for...
