Homework Statement
Two forces, vector F 1 = (4 i hat bold + 6 j hat bold) N and vector F 2 = (4 i hat bold + 8 j hat bold) N, act on a particle of mass 1.90 kg that is initially at rest at coordinates (+1.95 m, -3.95 m).
A) What are the components of the particle's velocity at t = 10.3 s?
Answer: 43.3i+75.9j
B) What are the components of the particle's velocity at t = 10.3 s?
Answer: 60.29°
C) What displacement does the particle undergo during the first 10.3 s?(Δr)
D) What are the coordinates of the particle at t = 10.3 s?
Homework Equations
The Attempt at a Solution
For C) I have tried every method I could think of to solve for Δr from multiplying the components of the particles velocity (A) by the time, to squaring each part and placing them under a √
D) I tried a lot for D too. I tried multiplying the coordinates given in the problem above by time, multiplying by the velocity components, and some other methods I can't remember, but nothing has come out right.
