A student runs toward the closed end of a hall while holding a vibrating tuning fork. The tuning fork is vibrating at 512Hz. The sound is reflected from the end of the hall back to the running student where 8.0 beats per second can be heard. Determind the speed of the student.

Problem
One block (3kg) is moving at 8m/s on a frictionless plane to collide with another block at rest with the same mass, but has a spring in front of it. Spring constant = 6 N/m
a. Determine the maximum distance the spring is compressed.
b. Determine the final velocities of the blocks...
Thanks for the input.
I used y = y' + vy't - 1/2gt^2
0 = 180m + 0 - 1/2(9.8m/s^2)t^2
4.9t^2 = 180m
t = 6s
So i would plug this into the horizontal velocity x = 80m/s(6s) = 480m
Thanks, is this correct? perhaps i was thinking way to hard earlier.
Problem
An air tanker flies horizontally at an altitude of 180 m and a speed of 80 m/s over a forest fire. In
order to hit its target with flame retardant chemicals, how far before it is directly over the target should it
release its load? Neglect air resistance.
Using Projectile motion...
