A bus carrying passengers starting from rest accelerates constantly over 10 seconds and reaches a speed of 50ms-1. a) Calculate the distance the bus moves during the last two seconds.

b) If there is a signal 1 km in front of the bus, will he be able to stop in time if he steps on the brakes, if he decelerates at 2 ms-2 ?

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
