A car starting from rest picks up at a uniform rate and passes three electric posts in succession. The posts are 360 m apart along a street road. The car takes 10 s to travel from the first post to the second post and 6 seconds to go from the second post to the third post.
3.59 According to the Guinness Book of World Records, the longest home run ever measured was hit by Roy “Dizzy” Carlyle in a minor league game. The ball traveled 188 mm (618 ftft) before landing on the ground outside the ballpark.1. How far would the ball be above a fence 3.0 mm (10 ftft) high if the fence was 116 mm (380 ftft) from home plate?
A prisoner, 1.80 meters in height, was discharged in consideration due to his advanced in age. In order to receive full pardon, he must run as fast as he can towards the country border 100 meters from the prisoner's position to be totally free. Unknown to the prisoner, he was not meant to be discharged alive, due to the heinous crimes he has committed. An archer with an exceptional accuracy, hidden from the prisoner, was 15 meters behind him. As soon as the prisoner started running at a rate of a = 0.012t, an arrow was released 30 seconds after the prisoner moved from rest, from a 2-meter high at an angle of 30 degrees above horizontal aiming at the middle of his body for a sure kill (neglect air resistance). a. What should be the initial velocity of the arrow if the prisoner was dead before reaching the country border?
A red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At time t= 0, the red caris at x, = 0 and the green car is at x, = 212 m. If the red car has a constant velocity of 27.0 km/h, the cars pass each other at x= 43.5 m.On the other hand, if the red car has a constant velocity of 54.0 km/h, they pass each other at x = 76.5 m. What are (a) the initialvelocity and (b) the (constant) acceleration of the green car? Please include the signs.
