"UNIFORM ACCELERATED MOTION in a VERTICAL PLANE. Falling bodies, near the earth, all have a uniform downward acceleration from the earth's gravity, G=32 ft/s^2 or 9.8 m/s^2. A uniform gravitation field G will result in VELOCITY at TIME and a distance, or HEIGHT, for the free fall. start at rest, initial velocity=0 | ----- G │ V │ gravity│ | HEIGHT V V │ <- VELOCITY at TIME ----------- Use these equations when velocity and time are important factors. G=gravity, V=final velocity at time T, H=distance traveled at time T. Enter value of gravity G and at least two other variables with nonzero values. (c) Copyright PCSCC, Inc., 1993 *** Answer to problem *** Type ? then (esc) 0 (enter) to set all variables to zero. Set the gravity to 32ft/s. Move the cursor to H and set the height to 24 ft. The impact TIME=1.22 s. Next move the cursor to T and type =TIME (enter). The impact velocity is 39.19 ft/s.
