A 20.0kg red curling rock travelling at 0.578m/s (W) strikes a stationary 20.0kg yellow curling rock head on. The collision takes 4.35x10^-2s. Immediately after the collision, the yellow rock moves off at 0.562m/s (w).

Using the info, which is true?

A) The collision is inelastic with about 5% of the total kinetic energy lost

B) The collision is inelastic with about 3% of the total kinetic energy lost.

C) The collision is inelastic with about 97% of the total kinetic energy lost.

D) The collision is elastic.

A 750-g disk sliding along frictionless ice with a speed of 8.5 m/s strikes a stationary rod-disk combo 12-cm from its center-of-mass. This rod-disk combo is made from a 360-g rod that is 35-cm long, with 2 150-g solid disks of radius 7.0-cm attached, one on each end of the rod. After the perfectly elastic collision, the disk moves off along a path that is 28º above its original path, while the rod-disk combo spins about its center-of-mass as it...

Two travelling sinosoidal electromagnetic waves, each with an intensity 5.0 W/m2 , interfere to form a standing wave. The resulting electric field E⃗ (z,t) has nodes (i.e., is zero at all times) at z=…,−2a,−a,0,a,2a,… with a = 7.0 m , and satisifes E⃗ (z,0)=0. Furthermore, the magnetic field B⃗ (z,t) is observed to point along ±i^ everywhere. You may take c = 3.0×108 m/s and 8.9×10−12 F/m .
