A rocket-powered hockey puck moves on a horizontal frictionless table.the figure(Figure 1) shows graphs ofvxandvy, thex- andy-components of the puck's velocity. The puck starts at the origin.
What is the magnitude of the puck's acceleration?
Hint: The x-component of the acceleration vector can be found by taking the dv_x/dt, which is the slope of the tangent at any point on a v_x vs t curve. A similar thing can be done to get v_y component. Use usual procedure to get magnitude of vector.
How far from the origin is the puck at t = 0 s?
How far from the origin is the puck at t = 7 s ?
How far from the origin is the puck at t = 8 s ?
