hd dompiet hotreceive full marks 6 marks) A racing car is traveling at a speed of 50 m/s on a -so mls circular track as shown. The driver, anticipating a straight section of the track, is accelerating the car at the rate of 2 m/s2. Determine the total acceleration of the car at this instant using the co-ordinate system shown. 1. (6 marks) A racing car is traveling at a spee a+ 13.14 j 200 m 2. (6 Marks) A crate weighing 96.6 lb is pushed up the 30 incline by a worker who pushes horizontally with a force magnitude P-200 lb. The coefficient of kinetic friction between the nclined plane and the crate is =0.1 Determine the acceleration of the crate.w,355 P-

Explanation / Answer

2) accelaration a = F/m
a = P*cos(30)-(mu_k*m*sin(30))-(0.1*96.6*cos(30))/96.6

a = ((200*cos(30))-(0.1*96.6*0.5)-(0.1*96.6*cos(30))/96.6 = 62.06

a = -1.65 m/s^2
