What is the horizontal range observed by a person

Reference no: EM13324835

A spring-loaded cannon aimed at 40 degrees above the horizontal is on the last car of a long train of flat cars. The train has an initial velocity of 58 km/h. At the moment the train begins to accelerate forward at 0.325 m/s2 , the cannon fires a projectile at 179 m/s. The cannon points in the direction that the train is moving.

a.) What is the horizontal range observed by a person standing on the ground?

b.) How far on the train from the cannon does the projectile land? Neglect air resistance.
