Learning Goal:To use the principle of linear impulse andmomentum to relate a force on an object to theresulting velocity of the object at different times.The equation of motion for a particle of mass m canbe written asEFdv= ma = mdtBy rearranging the terms and integrating, thisequation becomes the principle of linear impulseand momentum:t2ES F dt = m f dv = mv2 – mv1V1For problem-solving purposes, this principle is oftenrewritten asmvị +£ F dt = mv2The integral F dt is called the linear impulse, I,and the vector my is called the particle's linearmomentum.A tennis racket hits a tennis ball with a force of F = at – bt?, where a = 1200 N/ms , b = 500 N/ms? , and t is the time(in milliseconds). The ball is in contact with the racket for 3.05 ms . If the tennis ball has a mass of 62.6 g, what is theresulting velocity of the ball, v, after the ball is hit by the racket?Express your answer numerically in meters per second to three significant figures.• View Available Hint(s)vec?v =m/s

A 498-gram ball is traveling horizontally at 11.1 m/s to the left when it is suddenly struck horizontally by a bat, causing it to reverse direction and initially travel at 8.8 m/s to the right. If the bat produced an average force of 1.3 kN on the ball, for how long (in milliseconds) was it in contact with the ball?
A rubber ball (4 kg) falls from a height of 50 m and collides elastically with the floor. What is the velocity of the ball just after it rebounds from the floor?
An object of mass 5kg is given an initial downward velocity of 50 m/sec and then allowed to fall under the influence of gravity. Assume that the force in newtons due to air resistance is -10v, where v is the velocity of the object in m/sec. Determine the equation of motion of the object. If the object is initially 600 m above the ground, determine when the object will strike the ground. Assume that the acceleration due to gravity is 9.81 m divided by sec ^2 and let x(t) represent the distance the object has fallen in t seconds
