Your answer An object is fired from the ground at 124.52ft/sec at an angel of 34.35deg. along +x axis. Calculate the VERTICAL component of initial velocity * Your answer After 3.56 seconds, how far has the object traveled in feet horizozntally? * Your answer How high the object after 3.56 seconds* Your answerDuring WWI, the Germans had a gun called Big Bertha that was used to shell Paris. The initial velocity of the shell was 1700 m/s at an angle of 55° above the horizontal. Assume it returns to the same height as released. Ignore air resistance. 1. Find the total time in the air for the shell. 2. How far away did the shell hit? 3. Find the shell's velocity at the apex. 4.
