If the line 3x-4y = 0 is tangent in the first quadrant to the curve y = x^3 + k, then k is
Before starting this problem, review Multiple-Concept Example 6. The left ventricle of the heart accelerates blood from rest to a velocity of +20.6 cm/s. (a) If the displacement of the blood during the acceleration is +2.87 cm, determine its acceleration (in cm/s2). (b) How mu...
A cue ball (mass = 0.140 kg) is at rest on a frictionless pool table. The ball is hit dead center by a pool stick which applies an impulse of +1.60 N·s to the ball. The ball then slides along the table and makes an elastic head-on collision with a second ball of equal m...
A 54.5 kg. skateboarder starts out with a speed of 1.90 m/s. He does +80.0 J of work on himself by pushing with his feet against the ground. In addition, friction does -265 J of work on him. In both cases, the forces doing the work are nonconservative. The final speed of the s...
