Question

Problem 4: A projectile is fired with an initial velocity of 54.1 m/s, at an initial inclination of 33.7 degrees with the horizontal r-axis. All initial variables (displacement and time) start at 0. You are asked to consider two cases of motion for the projectile, one without drag, and one with drag, with both the cases including effects of gravity. a) For motion with no drag, acceleration vector is given as а -g, where g 9.8 m/s. b) For motion in the presence of linear drag, а =-001280-g, where v is the velocity vector at any instant in time. For both cases of acceleration, determine and compare the time taken to reach the peak of the trajectory, velocity at the peak of the trajectory, peak height reached, the range of the projectile, and the time of flight (total time taken to go from the starting position to the end of the trajectory along the horizontal direction)

Answer 1

I will be glad to see your comment if you have any query and thumb up if you are satisfied. Thanks...
