I used "2uSin(theta)/g" but the values that I put for "u" were like u2 > u1. And this is why I'm not sure of my answer and I doubt that it may be wrong.

Sorry to ask a stupid question but what do you mean by point? Can you please show me how would it be solved?

Homework Statement : The trajectort of two projectiles are shown in the figure. Let T1 & T2 be the rime periods and U1 and U2 be their speeds of projection. Then(state the answer with REASON): A) T2 > T1 B) T1 = T2 C) U1 > U2 D) U1 < U2 [/B] (MAYBE, MORE THAN ONE CORRECT) Homework Equations...

I don't have a camera right now and the laptop's camera isn't that good (it captued everything pixelated).

I figured out the formula for Ran I figured out the formula of range as: u2Sin2(theta)/g Can you tell me that how would it be done further?

Yep, that worked! I've got 2 seconds as the answer and hopefully it must be correct. Thanks :-)

Homework Statement : The trajectory of a projectile in a vertical plane is y = √3 x - (1/5)x2, where x and y are respectively horizontal and vertical distances of the projectile from the point of projection. Find the angle of projection and speed of projection.[/B]Homework Equations ...

hmm..Tried using kinematics equations but that landed me no where. Can you please show me that how will it be done?

Homework Statement : Question 1: A body is projected with speed u at an angle theta with the horizontal. Find the change in velocity in time t. Question 2: A body is projected with speed u at an angle theta with the horizontal. Find the speed of body at a height h. Both the questions are...

Homework Statement : A body is projected with 50m/sec at an angle of 53 degree with the horizontal. After what time velocity makes an angle 33.7 degree with horizontal. (tan 33.7 = 2/3)[/B] Homework Equations : Mostly from 2-Dimension and maybe calculus.[/B]The Attempt at a Solution : I've...
