C) A 0.315 kg bird flying along at 6.5 m/s sees a 0.019 kg insect heading straight toward it with a speed of 23 m/s (as measured by an observer on the ground, not by the bird). The bird opens its mouth wide and enjoys a nice lunch. What is the bird's speed immediately after swallowing the insect? Answer in m/s

D) A 2.6 kg block slides along a frictionless surface at 1 m/s. A second block, sliding at a faster 5.9 m/s, collides with the first from behind and sticks to it. The final velocity of the combined blocks is 2.9 m/s. What was the mass of the second block? Answer in kg

A 10 kg mass is sliding at 8 m/s along a frictionless floor toward an ideal massless spring. When the mass hits the spring, they stick together without any loss of energy. The mass stops briefly at x = +4.2 m before moving back toward equilibrium. (Assume x = 0 at the point at which the mass sticks to the spring and t = 0 when the mass first makes contact with the spring.)a)What is the spring constant of the...

A body of mass 15.0 kg is traveling at 5.3 m/s along the positive x-axis with no external force acting. At a certain instant an internal explosion occurs, splitting the body into two chunks of 7.5 kg mass each. The explosion gives the chunks an additional 16 J of kinetic energy. Neither chunk leaves the line of original motion. Determine the speed and direction of motion of each of the chunks after the explosion. Enter the larger velocity. Enter the...

The person’s mass, m= 68.1 kg, the unknown drag coefficient is, c , with units kg/s, and the local acceleration of gravity is g= 9.80 m/s2 . Our model for the person’s velocity vs time gave us a linear differential equation whose analytical solution was the following: V(t) = g*m/c*[1-exp(-c/m*t)]. Your job is to find “c”. You need to use the MATLAB “help” documentation to find the nonlinear curve fitting function and syntax for how to use it. Hint you...
