Homework Statement
A 5.1 kg penguin runs onto a huge sheet of frictionless Antarctic ice. At t=0 it is at x=0 and y=0 with an initial velocity of 0.39 m/s along the positive x-axis. It slides while being pushed by the wind with a force of 0.53 N directed along the positive y-axis. Calculate the magnitude of the penguin's velocity at t = 11.81 s.
Homework Equations
x = V0xt
y = Voyt + 1/2ayt2
The Attempt at a Solution
The penguin is traveling in the positive x direction and being pushed up in the positive y direction, so I need to find the horizontal distance and the vertical distance and then I can get the magnitude and angle from that. So I start by setting up a drawing on a coordinate plane where the penguin starts at the origin and it goes 0.39(11.81)m in the x direction but I don't know what I should do for the y direction. Any help is greatly appreciated.
