A boat which has a speed of 5km/hr in still water crosses a river of width 1 km along the shortest possible path in 15 min. The velocity of the river water in km/hr is………………?

Could you explain how?

One body is dropped and a second body is thrown downwards with an initial velocity of 1m/s simultaneously. The separation between these two bodies is 18m after a time……………….. ans:18 sec

A body starts from rest and falls vertically through a height of 19.6m . If g=9.8m/s2 then the time taken by the body to fall through the last metre of its fall is? Ans :0.05 sec please solve it..

A body starts from rest and falls vertically through a height of 19.6m . If g=9.8m/s2 then the distance travelled by the body in last 0.1 sec of its motion is….. ans 1.9m please solve it/

A body falls freely from the top of a tower and it falls 7/16th of the total distance in its last second. The time taken by the body for complete motion is….. ans:4 sec pz solve it.

a motor car covers 1/3 part of total distance with v1=10km/hr second 1/3 part with v2=20 km/hr and rest 1/3 part v3=60km/hr. what is the average speed of the car?

A body slding on a smooth inclined plane takes 4sec to reach the bottom, starting from rest at the top. How much time does it take to cover 1/4th dist from the top?
