Salmon often jump waterfalls to reach their breeding grounds.

Starting downstream, 1.99 m away from a

waterfall 0.468 m in height. at what minimum

speed must a salmon jumping at an angle of

30° leave the water to continue upstream?

The acceleration due to gravity is 9.81 m/s.

Answer in units of m/s.

Which graph represents motion with an object with positive velocity that is located at a position of 3 meters at a time of 0 seconds? a) a b) bb eliminate c) c d) d

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
