The figure shows a pendulum of length l = 2.8 m. its bob (which effectively has all the mass) has speed v0 when the cord makes an angle θ0 = 45° with the vertical. (a) what is the speed of the bob when it is in its lowest position if v0 = 6.0 m/s? what is the least value that v0 can have if the pendulum is to swing down and then up (b) to a horizontal position, and (c) to a vertical position with the cord remaining straight? (d) do the answers to (b) and (c) increase, decrease, or remain the same if θ0 is increased by a few degrees?

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
