Up! Up! Projectile

Actually this problem call to my attention because lots of my students were asking me how to compute the angle of this kind of problem so I decided to put it on blog for my Physics class.

Sample Problem for projectile at an angle:

A projectile is launched at acertain angle. After 5 seconds, it was observed that it hits the top of PCH DLSU building 1000m away. PCH DLSU building height is 100m. Find the angle of the projectile when it is launched.

Step 1: Write the Given: t = 5 sec; X = 1000m; Y = 100m and g = 9.8m/s^2

Step 2: Find the angle.




























Step 5: Answer = 12.54 degree
