Physics 3.5: Projectile Motion - Finding the Angle (2 of 4) Simple Case: Example

In this video I will calculate angle=? of a projectile fired at an angle at h=0 with initial velocity v0=20m/s traveling a distance x=40m.

Next video in this series can be found at:

just started further maths in the uk and were doing projectiles and i am so happy that when im not sure i have your clear explanations. i thank you for that.

This is (with the previous video) is the best video I can find on solving this problem!

Thanks for posting this.

Thanks a lot for all videos you did and all the upcoming ones All of your videos are very very helpful and all my doubts vanish away after watching your videos....
thanks again

Thank you for helping me with my ap physics c projectile motion homework

[quickhandymanservice]

Wow you are such a great lecture....its very easy to understand what you teach....thank you alot sir

[DetonatingD]

Thank you soo much for this, i have been looking for a proper Explanation for weeks now and i finally have found a good video explaining how to get the damm angle

chess man you make physics easy with your lessons keep it up

Hello professor, I have a very complicated question. It says here A cannon ball released at a speed of 15 m/s is fired at a certain angle. Determine this angle, given that the cannon ball landed 100 m from the cannon.

My calculator says I can't arcsin 4.36.

Im using this for a video game lmao thank you so much this was so easy to understand ❤

Oh! The equation we used to find the range of the projectile in earlier videos.

[delicousmangos]

arent there technically two launch angles that would work? if you think of it like this, whats the lowest point you can launch a ball with the shortest time to hit 40m, or whats the highest point you can launch a ball with the longest time to hit 40m. i tried deriving an equation with tangent, and i ended up with two angles that would both still reach 40m, only difference being the time it took.

Wow, that was so well-explained! Thank you so much1

stationary enemy ship is docked in the sea at distance of 1 km from the coastline. A gun located at the sea level on the coastline can fire projectiles at a velocity of 120 m/s. What is the angle in degrees) above the horizontal at which the gun must fire to hit the ship? (g =

My answer :21.42

thank you so much, this helped me tremendously!!!

Sir please upload Required angle solution for incline projectile motion

[crowdedboss]

Why do we use Sin? not Cos? Since we have the adjacent side and the hypotenuse. We don't know the opposite side so why do we use Sin? Clarification would be appreciated

[jaylisarapa]

Sir, I have some questions.Would you help me.

[Emma-odqx]

what if the ball is thrown in an horizontal angle.would we find the angle in the same way?
