Q. A train 400m long is moving on a straight track with a speed of 84.30km/h. The engineer applies the brakes at the crossing and later the last car passes crossing with the speed of 17.7 km/h. suppose constant acceleration; conclude how long the train blocked the crossing. Disregard the width of the crossing.

Q. Throughout a hard sneeze, your eyes might shut for 0.48s. If you are driving a car at 97 km/h during such a sneeze, how far does the car move during that time?
