So, I learned about projectile motion in class a fe days ago, and am having trouble understanding. I main problem is seeing how velocity works in projectile motion. For example, why is the velocity in the x direction always the same?
It would also be really helpful if you can do the example below:
In 1993,Wayne Brian threw a spear a record distance of 201.24 m. Suppose Brian threw the spear at a 35.0° angle with respect to the horizontal. What was the initial speed of the spear?
please, and thank you
