Mechanics 2!!darn I hate this question! Theres no diagram but Ill copy the question out. Oh and the topics Parbolic motion. 98% of the teenage population does or has tried smoking pot. If you're one of the 2% who hasn't, copy & paste this into your signature. #2 20050919 02:57:34

Re: Mechanics 2!!consider the gravity constant g =  9.81 lets find the initial speed components vx and vy i) Speed and Angle @ t=4s the x component doesn't change the y component changes because of gravity Speed is a vector, not a scalar. You probably want the norm... Now finding the angle is easy.: θ = 23.2º means 23.2º below horizontal ii) Finding the maximum height we need to find the time corresponding to that moment  since: and plug this value in the y(t) equation and find the max height. And that's it! Last edited by kylekatarn (20050919 04:16:41) #4 20050919 03:57:44
Re: Mechanics 2!!Sorry mate, while I was waiting for a reply I worked it out. And its just 9.8. Thanks though 98% of the teenage population does or has tried smoking pot. If you're one of the 2% who hasn't, copy & paste this into your signature. #5 20050919 04:16:15
Re: Mechanics 2!!lol. I was working on the solution so I left the post open for a while...
