Mechano, the evil robot cat, has captured the mous
Mechano, the evil robot cat, has captured the mouse, Jerry (mJ = 0.500 kg), and is about to launch him out of a window using his robotic sling shot.

Part A: You can see that the sling shot has two elastic bands that hold the pouch, which is wrapped around Jerry. Treat each of the bands like a Hooke\'s Law spring, with a spring constant of k = 1800 N/m. The rest length of each \"spring\" is L0 = 0.0550 m. At the time of the launch, the \"springs\" have a length of Lf = 0.100 m.

Part B: What is Jerry\'s speed (vJ) when he leaves the sling shot?

a) potential energy in the spring = 1.8225 J

b) Jerry's speed = 2.744 m/s

Explanation:

a) The spring constant, k = 1800 N/m

The rest length of the spring,

The launch length,

The potential energy of each spring is ,

PE = 1.8225 J

b) To get Jerry's speed, use the law of energy conservation

PE energy in the string = KE of the robot

PE in the spring = 1.8225 J

v = 2.744 m/s

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
