Question

A bullet had a speed of 62 m/s at the peak of its trajectory. The time elapsed from the launch of the bullet to the peak of its trajectory was 7.7 seconds. The bullet fell 21 meters from the peak of its trajectory to its impact. What was the launch speed of the bullet? What was the speed of the bullet at impact? Don't assume that the time and displacement in the y-direction from launch to peak are the same as peak to impact. Please include a diagram and a clear explanation of the solution.

Answer #1

A bullet is launched with an initial speed of 1245 m/s. The
initial velocity in the y-direction is 515 m/s and the initial
velocity in the x-direction is -1208 m/s. When the bullet reaches
the peak of its trajectory, what is the velocity and the
acceleration in the x-direction and what is the velocity and the
acceleration in the y-direction? Consider up to be positive. Please
include a diagram and an explanation of each step. Do you use the
max...
