Kinematics

A float is overcome by a Motor Boat going downstream at a point A. T hours later it turns Back and after some time it passes the float at a distance d km From point it. What is the velocity of Stream if the speed of motor Remains constant w.r. to water.?

Answer: u = d/2T

A car accelerate from Rest with a =2m/s2 in a straight track. It comes to Rest by applying it’s Breakes after time T= 20 seconds after covering a distance of 100m. using a graphical method. find the maximum speed of car.
