Find the impulse of a 50. kg object under the following scenarios:
a. The object accelerates to 7.5 m/s from rest.
b. The object stops from a velocity of 12.0 m/s.
c. The object change in velocity from 2.2 m/s to 6.3 m/s.
d. The object hits the ground with 2.5 m/s and rebounds with the same speed

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
