Question

A spring-loaded cannon aimed at 44 o above the horizontal is on the last car of a long train of flat cars. The train has an initial velocity of 57 km/h. At the moment the train begins to accelerate forward at 0.305 m/s2 the cannon fires a projectile at 181 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 from the cannon on the train does the projectile land? Neglect air resistance.

BOTH PART A AND B PLEASE

Explanation / Answer

this are the steps to solve the problem, just change the numbers and you will be fine.

v1 = 57/3.6 = 15.83 m/s

t = 2Vsin?/g = 2*184*sin47
