A chauffeur heads south with a steady speed of v, - 22.0 m/s for t, - 3.00 min, then makes a right turn and travels at v, - 25.0 m/s for ty- 2.20 min, and then drives northwest at v, 30.0 m/s for t, 1.00 min. For this 6.20-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 direction (b) average speed (in m/s) m/s M south of west (c) average velocity (Enter the magnitude in m/s and the direction in degrees south of west.) m/s magnitude direction south of west

A ball is thrown upward from a height of  1.6 m  at an initial speed of  24 m/sec. Acceleration resulting from gravity is −9.8m/sec2. Neglecting air resistance, solve for the velocity v(t) and the height h(t) of the balltseconds after is is thrown. Ans...Velocity v(t)=_________meters/second

Usually, Tony travels to Bunbury from Perth city in 2.50 hours. One day he increases his average speed by 12.0 km/h and takes 22.5 minutes less time to reach Bunbury. (a) What was his usual average speed? What was the distance travelled? (b) On the way he stopped at a rail crossing (6.00 m wide) and a train (total length 144m) decelerating at -0.585 ms2 just entered the crossing with a velocity of 13.7 m s¹. Sketch a diagram and find the minimum time for the last carriage of the train to clear the crossing.

Two airplanes leave an airport at the sametime. The velocity of the first airplane is680 m/h at a heading of 51.6◦. The velocityof the second is 640 m/h at a heading of 176◦.How far apart are they after 2.3 h?Answer in units of m.
