Free-body diagrams A free-body diagram can be used to show the magnitude (size) and direction of each force acting on
an object. The object is represented by a small circle, and all force arrows start from the centre of the
circle.
Draw free-body diagrams for the following:

Upthrust of the water
40,000 N
Weight of the boat
40,000 N

0.11 m/s and 0.28 m/s should be correct

neither accurate nor precise.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
