A Gray Kangaroo Can Bound Across a Flat
A greyness kangaroo can spring across a flat stretch of ground with each spring carrying it 10.00m from the takeoff indicate. (a) If the kangaroo leaves the footing at a 20.0angle from the horizontal, what is its takeoff speed? Express your answer to three significant figures and include the appropriate units. (b) What is its horizontal speed?

who? Then this is a projection of motion question. So just attempt and draw something here. Nosotros got yous know, something like this. Yes. Okay. So there's going to exist the hearts. The question was giving u.s.a. ten m. The music has the uh the angle you know, Which is xx°. Uh huh. Then let'south do the speed. Take off the C. V. Okay. Then because this motion it's two dimensional. Nosotros need to endeavor and mother it as such. So, you know that the uh velocity is going to take to component. We're gonna accept a component that fashion. That's gonna be a V. Thank you. We're gonna have another component this way. He'due south going to be toll information. Correct? Then you're going to look at the vehicle component using Newton's equations, correct? Then we're gonna reason fee squared considering U squared Uh huh. Us two Gs. And then here at the maximum height Being quite zip. All correct. Music from nil Indonesian velocities. Our contempo era in a vehicle country. Right. Then, uh, it's going to be the hero equals. And the wire directory humvee I squared minus is going up to Yes. All right. Who us? Uh, okay. We find any of you. So just gonna isolated. Allow's just say it to Gs has been a V squared a scientific discipline. Slap-up peter Okay. We find the speed of take off. So The spread is going to be 42 G. S over. So that'southward great. Peter. Right? And then the takeoff speed is only the square root of that. two G. S. My sons were data. And so our commutation. So your 2009.eight times turn correct. The height is 10 or uh so 20 squared. Okay allow's see. So y'all have foursquare root. Uh huh. Mm hmm. Uh huh. Why don't you do right past sign torn eject. Yeah for certain. Okay. So this speed of takeoff takeoff speed, that's gonna be family for a month meters per 2nd. Okay. So it's going to have off speed for the second office. You desire to notice a horizontal speed? It's a diagram. The horizontal speed are merely gonna be vehicles data. All right. Uh huh horizontal speed is going to be mm. Costa is gonna be funny on my cost to him. Mm A very times close to. So the horizontal speed is going to be here 38 or why read this with seconds. Okay. Thank y'all very much.
