A 400 g particle moving along the x-axis experiences the force shown in Figure Ex11.15. The particle goes from vx = 2.5 m/s at x = 0 m to vx = 5.5 m/s at x = 2 m. What is Fmax?
my solution manual told me to do this with work and energy
but why can't i do
kinematic:
5.5^2=2.5^2+2A2=6
F=ma
(0.4KG)(6m/s^2)=.5Fmax(2)=2.4N
area under the curve--triangle---
but the correct answer is 4.8N...ugh
