Problem Details
A rocket-powered hockey puck moves on a horizontal frictionless table. The figure below shows the graphs of vx and vy, the x- and y-components of the puck’s velocity. The puck starts at the origin.

A figure shows two graphs of the x and y components of the velocity as functions of time. Both graphs have time measured from 0 to 5 seconds on the x-axis and velocity components measured from 0 to 40 centimeters per second on the y-axes. The x-component of the velocity rises linearly from 0 to 40 centimeters per second in the time interval from 0 to 5 seconds. The y-component of the velocity keeps the constant value of 30 centimeters per second through the whole time period.
