In a loop-the-loop ride a car goes around a vertical, circular loop at a constant speed. the car has a mass m = 228 kg and moves with speed v = 16.74 m/s. the loop-the-loop has a radius of r = 11.3 m.
1.what is the magnitude of the normal force on the care when it is at the bottom of the circle? (but as the car is accelerating upward.)
2.what is the magnitude of the normal force on the car when it is at the side of the circle (moving vertically upward)?
3.what is the magnitude of the normal force on the car when it is at the top of the circle?
4.compare the magnitude of the cars acceleration at each of the above locations:
a. abottom = aside = atop
b. abottom < aside < atop
c. abottom > aside > atop
5.what is the minimum speed of the car so that it stays in contact with the track at the top of the loop?

As shown in fig. p3.64, a closed, rigid tank fitted with a fine-wire electric resistor is filled with refrigerant 22, initially at 2108c, a quality of 80%, and a volume of 0.01 m3. a 12-volt battery provides a 5-amp current to the resistor for 5 minutes. if the final temperature of the refrigerant is 408c, determine the heat transfer, in kj, from the refrigerant.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
