= A race car drives a circular tract as shown in the figure with its velocity expressed as v 5t3 8 where v is in m/s while t is in seconds. Determine its acceleration when t is equal to 2 secon and radius of curvature is 4m.

Find the magnitude of the instantaneous acceleration (in m/s²) of an object that moves at a constant speed around a circle if it take it 4.24 s to complete one revolution. The radius of the circle is 2.52 m.

: A motorist is traveling on a curved section of highway of radius 2500 ft at the speed of 60 miles per hour. The motorist suddenly applies the brakes, causing the automobile to slow down at a constant rate. Knowing that after 8 seconds the speed has been reduced to 45 miles per hour, 1. Determine the acceleration of the automobile immediately after the brakes have been applied. VA = 60 mi/h A 2500 ft

A car travels at a constant speed of 16.5 m/s around a circular track that has a radius of 236 m. What acceleration does it experience?

Find the magnitude of the instantaneous acceleration (in m/s2) of an object that moves at a constant speed around a circle if it takes 7.01 s to complete one revolution. The radius of the circle is 1.62 m

3. F(t) = 2ti - 2tj + tk
