Angle plus horizontal velocity,

[trustabdy]

if an object is fired at a 20 degree angle and has a horizontal velocity of 30m/s, what is the vertical displacement, how long the ball is in the air, horizontal displacement, original velocity of the ball?

help?

You need to show some work. Do you have any relevation equations for projectile motion?

 

[trustabdy]

basic motion - free falling body. range is straight line

 

[hotvette]

basic motion - free falling body. range is straight line

OK, so what are the applicable equations for basic motion - free falling body and how does that relate to the problem statement?

 

[trustabdy]

if u help me find the initial velocity or time i could find the the problems myself

 

[hotvette]

The easiest part is the initial velocity. You are given an angle and the horizontal component of the velocity. Draw a triangle and use some trig.

okay i can't do t the trig and i have a test tommorow please show me how to do it

 

[trustabdy]

never mind i got it. thanks for reminding me about the trig
