Q. Starting from rest, a boat increases its speed to 4.07 m/s with constant acceleration.

What is the boat's average speed?

If it takes the boat 4.67 s to reach this speed, how far has it traveled?

Q. When a high-speed passenger train traveling at 101 km/h rounds a bend, the engineer is shocked to see that a locomotive has improperly entered onto the track from a siding and is a distance D = 671 m ahead. The locomotive is moving at 25 km/h. The engineer of the high-speed train immediately applies the brakes. What must be the magnitude of the resulting constant deceleration if a collision is to be just avoided.
