A motorist is travelling on a curved section of highway of radius 800 m at a speed of 80 km/h. The motorist applies the brakes, causing the car to slow down at a constant rate. Knowing that after 5 seconds the speed has been reduced to 60 km/h, determine the magnitude of the car’s acceleration
(a) immediately after the brakes have been applied, and
(b) 5 seconds after the brakes have been applied.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
