A projectile is launched at 65 m/s at an angle of 40 degrees. Find:

a) the final velocity (as two components and as a magnitude and direction)

b) the total time of flight

c) the maximum height

d) the horizontal range.

 

Thanks for your help!

i hope you don't expect us to give you the answers, you're supposed to work them out for yourself.

 

a)this is obvious it is just trigonometery <--- BIG hint!

 

b) equations of motion

 

c) equations of motion

 

d) equations of motion

 

now go try them for yourself.

I think the hint was in the question. Break the motion into the two components, x and y. Remember that only the y component is affected by gravity. The velocity in x will be constant.
