I am taking physics 11 university preperation physics class, and I am struggling with understanding on how to approach and solve projectile motion problems. Now fortunautly, this is the last thing we are learning in kinematics. From what I know about this, the acceleration is always a = -9.8m/s2, and I have to create 2 equations for horizontal and vertical sides. I do always draw a diagram to help me visualize this, but I still am struggling to how to approach it.

In these problems, do I have to at least make 2 equations to get the answer I need?

A man runs 2.5 km north and then 1.5 km in a direction 30◦ east of north. A woman walks directly between the same initial and final points. What distance does the woman walk? In what direction?

I know this seems easy but my answer just seems to keep on coming out wrong and I cannot make the diagram for this properly. Can someone please help me out and solve this question :( ik its easy vector addition nd resolution into components and ik whats happening but i jsut dont understand why

Hi, I’m a first year student in physics and I’m having a hard time doing excersizes and solving problems. My problem is really that I can understand the concepts from class well enough and remember formulas and what not, but I can never seem to understand how to solve anything or apply my knowledge to tasks I’m given. It seems like all my classmate are able to just immediately start doing excersizes but I’m stuck not knowing where to start. I’m wondering if anybody has any tips or have been through the same as me. Any replies are appreciated)
