Q1. An aluminium block of mass m1 = 3.45 kg and a copper block of mass m2 = 6.30 kg are connected by a light string over a frictionless pulley. They sit on a steel surface, where θ = 40.0°
Q2. A 2.82 kg object on a frictionless horizontal surface oscillates at the end of a spring with amplitude of 7.88 cm. Its maximum acceleration is 3.34 m/s2. Compute the total mechanical energy.
You have a 56.9-mF capacitor initially charged to a potential difference of 10.1 V. You discharge the capacitor through a 4.77-Ω resistor. What is the time constant? After what multiple of the time constant does the potential difference reach 2.47 V.
According to the Guinness Book of World Records (1990 edition, p. 169), the highest rotary speed ever attained was 2010 m/s (4500 mph). The rotating rod was 15 cm (5.9 in) long. Imagine the speed quoted is that of the end of the rod.
