A rocket is launched at an angle of 50.0° above the horizontal with an initial speed of 95 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 29.0 m/s². At this time, its engines fail and the rocket proceeds to move as a projectile.

(a) Find the maximum altitude reached by the rocket.

(b) Find its total time of flight.

Expert Solution

The answers are in the images. Page number is mentioned at right top. Here the given acceleration of the rocket is a = 29 m/s² . As not clearly mentioned, as convention, here I consider this acceleration given here is considering the effect of gravitional acceleration, i.e net effect means the acceleration of rocket is given. If it is not, you just need to subtract the value of g from upward acceleration a_y i.e (a_y - g) = (22.21 - 9.81) = 12.4 as net upward acceleration and do the same method to solve the problem. However, as per problem statement and general convention, my calculation is right.

A shell is launched at angle 62° above the horizontal with initial speed 30 m/s. It follows a typical projectile-motion trajectory, but at the top of the trajectory, it explodes into two pieces of equal mass. One fragment has speed 0 m/s immediately after the explosion, and falls to the ground. How far from the launch-point does the other fragment land, assuming level terrain and negligible air resistance?
