From point A located at the perimeter of a circular forest of diameter 30 km we want to reach the farthest point B of the forest. There is a straight footpath BC passing through the forest. Through the trees we can walk with speed 3 km/h, along the pathway the speed of walking is 5 km/h. Find the shortest possible time needed to reach point B?

A cat falls from a tree (with zero initial velocity) at time t = 0. How far does the cat fall between t=0.3s and t = 1.4 s? Use Galileo's formula u(t) = 32t fus. Answer: ft.

A train starts from rest and accelerates uniformly, until it has traveled 5.6 km and acquired a velocity of 42 ms. The train then moves at a constant velocity of 42 m/s for 420 s. The train then slows down uniformly at 0.065 m/s2, until it is brought to a halt. The acceleration during the first 5.6 km of travel is closest to: O 0.20 m/s² O 0.14 m/s² O 0.19 m/s² 0.17 m/s² O 0.16 m/s²
