A class of physics students is investigating projectile motion using a variety of equipment. Assume air resistance can be ignored in all cases. One group constructs a long ramp as shown in Ramp 1 below. In their experiment, they release a disk from the left side of the ramp and allow the disk to launch off the right side. The ramp is smooth enough that friction can be ignored. The left side of the ramp is supported by the top of a shelf, and the other side is supported by the top of a desk. The left and right sides of the ramp are at angles 81, and gy with the horizontal respectively. Ceiling Geiling o Initial Disk , Initial Disk Position Position ote: Figures not drawn to scale. The students release a disk and measure the maximum height it reaches after leaving the right side of the ramp. The students then adjust the ramp so that Ay
