4. Collision (10 points): You are sitting in a car that moves along the $$x$$-axis. You are currently at the point $$(?50\mathrm{m},0)$$ moving at a constant speed of $$5\mathrm{m}/\mathrm{s}$$ toward the origin. A high schooler is also in a car but is traveling along the $$y$$-axis starting from rest at $$(0,?100)$$. The high schooler. has his foot on the gas all the time and is accelerating at a constant rate. What should this acceleration be so you two have a really bad day (collide)? Solve this in both your frame and a frame fixed to the earth.
