Problem: A model rocket is launched from rest with an upward acceleration of 4.50m/s2 and, due to a strong wind, a horizontal acceleration of 1.50 m/s2.
Part A: How far is the rocket from the launch pad 6.50s later when the rocket engine runs out of fuel?
Please write the step to find how far is the rocket from the launch pad 6.50s later when the rocket engine runs out of fuel.
