If anyone can help with my last assignment question please.

A car accelerates along a straight road with a uniform acceleration when it passes A it has a speed of 12m/s and when it passes B it has a speed of 32m/s. points A and B are 1100m apart. Determine the time taken to move from A to B.

 nescio using the equations v^2 = u^2 + 2as and v = u + at, where u=initial speed, v=final speed, a=acceleration, s = distance travelled and t=time and rearranging, you get t = 2s / (v+u) =2200/44 = 50 m 23:17 Sat 23rd Jun 2012 Go To Best Answer
