Question1

A 1000 kg car carrying four 76 kg people travels over a rough "washboard" dirt road with corrugations 4.0 m apart which causes the car to bounce on its spring suspension. The car bounces with utmost amplitude when its speed is 23 km/h. The car now stops, and the four people get out. By how much does car body rise on its suspension owing to this reduce in weight?

Question2

A bus travels 310 km south along a straight path with an average velocity of 82 km/h to the south. The bus stops for 22 min, then it travels 240 km south with an average velocity of 69 km/h to the south. How long does the total trip last?

Response in units of h

Question3

A motorist drives south at 20.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.00 min, and finally travels northwest at 30.0 m/s for 1.00 min. For this 6.00-min trip, find out-

(a) Total vector displacement,

(b) Average speed, and

(c) Average velocity. Let the positive x axis point east.
