It bends light rays outward.<span>A concave lens causes light rays passing through to spread apart.</span>
Two in middle, so Newton's 2nd law. Equal and opposite force (both are moving). You have to assume no friction since it's an ice rink.
<span>Skater 1: 45kg 0.66m/s </span>
<span>Skater 2: xkg 0.81ms/ </span>
<span>Since force is equal, 45*0.66=x*0.81 </span>
<span>Solve for x. </span>
<span>So the answer would be 36.7kg</span>
Answer:
The man fires an 80 g arrow so that it is moving at 80 m/s when it hits and embeds in a 8.0 kg block resting on ice. how far will the block slide on the ice before stopping? a 7.1 n friction force opposes its motion.
