## JD's Assessment Test

1.

Two cars A and B are at the same point at t=0. B travels with constant velocity and A travels with constant acceleration. Their velocity vs. time graph is given below. After how many meters they become together?

2.

Velocity of the river with respect to ground is 2m/s to the east. Width of the river is 80m. One boat starts its motion on this river at point A with a velocity shown in the figure below. Find the time of the motion and horizontal distance between the arrival point and point A.

A river boat in a river having constant velocity travels 120m distance from point A to B in 20 s and turns back from B to A in 12 s. If the velocity of the river is zero, find the time of this trip.
