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.
2. A motorist saw a humps 33 m away at a speed of 14.5 m/s. He immediately slams on the brake and decelerates 1.2 m/s 2 with a speed of 11.7 m/s. (a) Will he stop before the humps (express your answer in magnitude)? (b) How long it will take before stopping?
(a) If a flea can jump straight up to a height of 0.440 m, what is its initial speed as it leaves the ground? (b) How long is it in the air? Note: Round off your answers in the nearest hundredth.
The other day, while riding my bike, I was forced to stop quickly to avoid a squirrel in the middle of the road 60 feet ahead. I decelerated at a constant rate of 15 ft/sec², skidding all the way. One second into the slide, my trip computer said I was going 27 ft/sec. How far did I skid before stopping? Did I avoid hitting the squirrel? Round to the nearest tenth
