Question

An Estes toy rocket accelerates in a straight line direction from the ground at 27.0 m/s2, and at an angle of 53.0° above the horizontal while the engine is burning fuel. The rocket fuel burns out after 3.7 s and the rocket takes a projectile path to the ground. Find its horizontal distance from the launch point to where it hits the ground. in M
