Question

1) A particle of mass m, moving in the x-y plane, penetrates a certain material, undergoing the action of a force given by \( \vec{F} = F_0 \hat{x} - b \left( \frac{dy}{dt} \right)^2 \hat{y} \), where \( F_0 \) and \( b > 0 \) are constant. At this moment, at \( t = 0 \), the particle is in position \( \vec{r} (t = 0) = (0, 0) \), with initial velocity \( \vec{v} (t = 0) = v_{0x} \hat{x} + v_{0y} \hat{y} \). a) Calculate the position vector \( \vec{r} (t) \) of the particle. b) Find the particle's path equation for the case where \( v_{0x} = 0 \). Sketch \( y(x) \) x \( x \) for this situation.

1) A particle of mass m, moving in the x-y plane, penetrates a certain material, undergoing the action of a force given by F⃗ = F0 x̂ - b ( (dy)/(dt))^2 ŷ, where F0 and b > 0 are constant. At this moment, at t = 0, the particle is in position r⃗ (t = 0) = (0, 0), with initial velocity v⃗ (t = 0) = v0xx̂ + v0yŷ.
a) Calculate the position vector r⃗ (t) of the particle.
b) Find the particle's path equation for the case where v0x = 0. Sketch y(x) x x for this situation.
