The world record in high jump was set in 1993 by Javier Sotomayor. The height of the record jump was
2.45 m (that's just over 8 feet!). Javier is 193 cm tall. Treating his body as a point located at half his
height and given that he left the ground at a horizontal distance of 1.5 m before the bar at a takeoff
angle of 65.0, the goal of this problem is to find his initial speed. (Ignore air resistance and take the
acceleration of gravity to have a magnitude of 9.8 m/s?).
1) Set-up: Draw a diagram of the jump. Label what is known and what is unknown.
2) Solve: Using the known information, use the equations of motion to find both the horizontal and
vertical components of the initial velocity.
3) Solve: What is the initial speed.
4) Reflect: Are the units correct? For (2) are your signs correct for the horizontal and vertical velocities
given how you drew your coordinate system? Is the magnitude of (3) reasonable? For your reference the
fastest sprinters can run at about 10 m/s.
