## Homework Statement

A spring-loaded cannon aimed at 47 degrees above the horizontal is on the last car of a long train of flat cars. The train has an initial velocity of 54.3 km/h. At the moment the train begins to accelerate forward at 0.325 m/s2 , the cannon fires a projectile at 180 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

## Homework Equations

x=Vi*t+ 1/2a(t)^2

## The Attempt at a Solution

I know that x component is 180cos 47 and y component is 180sin 47. Not sure where to go from here
