A boat is stationary at   away from a dock. The boat then begins to move toward the dock with an acceleration of  .How long will it take the boat to reach the dock?Your answer should have two significant figures.

A boat is pulled into a dock by a rope attached to the bow of the boat and passing through a pulley on the dock that is 1 m higher than the bow of the boat. If the rope is pulled in at a rate of 1 m/s, how fast (in m/s) is the boat approaching the dock when it is 5 m from the dock? (Round your answer to two decimal places.)

The time taken by a boat to go to a certain distance against the current is the same as to go the double distance along the current. The speed of the current is 3 km/h. How much time will the boat take to travel 57.6 km in still water?

A boat, initially at rest, travels 20 m in 4.0 seconds along a straight path with constant acceleration. What is the acceleration of the boat (in m/s2) ?

9. A speedboat starts from rest and reaches a velocity of 20 m s-1 in 10 seconds. It continues at this velocity for a further 5 seconds. The speedboat then comes to a stop in the next 4 seconds. (i) Draw a velocity-time graph to show the variation of velocity of the boat during its journey. (ii) Use your graph to estimate the velocity of the speedboat after 6 seconds. (iii) Calculate the acceleration of the boat during the first 10 seconds. (iv) What was the distance travelled by the boat when it was moving at a constant velocity?

The speed of a boat in still water is 6 kmph and the speed of the stream is 1.5 kmph. A man rows to a place at a distance of 22.5 km and comes back to the starting point. The total time taken by him is?Options10 hours6 hours 10 minutes8 hours4 hours 10 minutes
