Planet $\mathbf{X} !$ When venturing forth on Planet $X,$ you throw a 5.24 kg rock upward at 13.0 $\mathrm{m} / \mathrm{s}$ and find that it returns to the same level 1.51 $\mathrm{s}$ later. What does the rock weigh on Planet $\mathrm{X}$ ?

Carter kind of Exeter, Iraq upwards with velocity. Initial velocity of 13 meters per second squared cash itself choosing valises, choosing upwards as the positive direction and self we to find the acceleration that it caused by that acceleration due to gravity on the surface of the rock. What? From the fact that it took 1.51 seconds for it to come back to the state position, we use an equation of motion. This is why position equals initial. Why not? Bye. US initial velocity times. T velocity times T Uh, plus 1/2. Okay. Tardes, 18 squared. Sorry tray. And so when it comes back to the same position s so you start off with zero. So you weren't here. When it comes back to the same position, why will also be zero? So why? And why not out? What we're left with is not cheap. Plus 1/2 a T squared equals zero. So you re arrange that. Can you get Katie calls? Negative. Too keen on over tea. Okay. And so this is negative. Two times 13 meters per second. And I'm so sorry. I just realized that the second squared over use second because its velocity if and she divide that by time is one part five seconds. And so what you get is negative. 17 or two meters per second squared just mean since I've acceleration. Hacking downwards, uh is some 17 for two years for seconds. This means that cheen, which is exploration beauty gravity, will just be 17.2 meters per seconds. Greg, because it's already act downwards, huh? And sells best. It's our basically used your second law. Had she force equals she and G is deceived by the way. Not that you young birth. We're on a rock here Planet X and so M is 5.4 kilograms. Maciver check and she is 17.2 years second squared That gives us 90 point to news is awake measured, of course, different on Earth. We healthy ci on our best effort and that's it
