|| DATA A projectile is fired horizontally at a speed of 15 m/s from the top of a 200-m-high cliff on Planet X. After it is fired, the height h of the projectile above the base of the cliff is measured as a function of time. The resulting data are shown here:
Time (sec) | h(m) |
1.0 | 190 |
2.0 | 160 |
3.0 | 110 |
4.0 | 40 |
Make a linearized plot of these data with h on the y axis. Draw a best-fit line through the linearized data and use this line to estimate (a) the acceleration of gravity for Planet X, (b) the time when the projectile reaches the bottom of the cliff, and (c) the horizontal distance the projectile lands from the base of the cliff.
