A car is traveling at 72.0 km/h, when the driver notices an overturned truck blocking the road 95.0 m ahead. The car travels at 72.0 km/h for 0.50 s before the driver applies the brakes. (Please show work). (a) How far does the car travel in that 0.50 s?

(b) If the car has an acceleration of -2.50 m/s², will it be able to stop before reaching the truck? If not, how fast is the car traveling when it collides with the truck?

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
