A shell is fired 2.50 m above level ground with an initial speed of 35.0 m/s at an ngle of 30.0 ° above the horizontal on a long flat firing range. Targets that are 5.00 per side are placed flat on the ground at marks 100.0-105.0 m, 150.0-155.0 m, D0.0-205.0 m, and 250.0-255.0 m from the end of the barrel. Determine (a) the tal horizontal distance covered and if a target is hit (b) the maximum height ached by the projectile above the ground, (c) the total time in the air, and (d) the locity vector of the projectile 3.00 s after firing.

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
