2-Dimensional motion query

  1. Jul 28, 2015 #1
    1. The problem statement, all variables and given/known data:
    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 somehow related and that's why I've included both question in one thread.

    2. Relevant equations: Equations from 2-D Kinematics and vector and maybe some calculus.

    3. The attempt at a solution:
    I tried to use dv/dt but I'm not able to figure out that to what quantity/value should it be equal. And it's throwing me off :/

    You really don't need to use calculus here. Can you try and set up the kinematics for it?

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

    Can you show your work?

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

    You should not be trying to post images of your own algebra. That's for pages from books and diagrams. Take the trouble to type your working into a post, preferably using LaTeX.
