A bus driver heads south with a steady speed ofv1 = 22.0 m/sfort1 = 3.00 min, then makes a right turn and travels atv2 = 25.0 m/sfort2 = 2.80 min, and then drives northwest atv3 = 30.0 m/sfort3 = 1.00 min. For this 6.80-min trip, calculate the following. Assume +x is in the eastward direction.(a)total vector displacement (Enter the magnitude in m and the direction in degrees south of west.)magnitude m direction ° south of west(b)average speed (in m/s)m/s(c)average velocity (Enter the magnitude in m/s and the direction in degrees south of west.)magnitude m/s direction ° south of west

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
