1. In a circular motion, the radius r = 20 m, and the tangential speed v = t² + 1, where t is in unit s and v is in unit m/s. What are magnitudes of the instantaneous tangential acceleration and centripetal acceleration at t=3 s?

2. A car of mass m moves on a frictionless road. At t = 0, the driver shuts the engine off, and the car has speed v₀. After that, the only force acting on the car is the air drag force: , where A is a constant, and v̄ is the velocity. For t ≥ 0, find the speed of the car as a function time t.

6. A uniform spherical planet has mass M and radius R. A very thin tunnel passes from one end of the planet, through the planet center, and then out from the other end of the planet. A particle of mass m fell into one end of the tunnel and then performed simple harmonic motion. Find the angular frequency of the simple harmonic motion.
