A) A bowling ball is given an initial speed v0 on an alley such that it initially slides without rolling. The coefficient of friction between ball and alley is µ. Find the speed of the ball’s center of mass vCM at the time pure rolling motion occurs. B) Since the frictional force provides the deceleration, from Newton’s second law it follows that aCM = µ g. Find the distance x it has traveled. When pure rolling motion occurs, vCM =...

A cannonball is fired at a cliff of height h with an initial speed of v0 = 42.0 m/s directed at an angle of θ = 60.0° above the horizontal. The cannonball strikes point A precisely 5.50 s after it is launched. Ignore air resistance. a) Find the maximum height the cannonball reaches, H. b) Find the height of the cliff, h. c) Find the velocity of the cannonball the instant before it strikes point A. Give your answer in...

Question 56) PART 1) In the figure an electron is shot at an initial speed of v0 = 4.62 × 106 m/s, at angle θ0 = 40.9 ˚ from an x axis. It moves through a uniform electric field = (5.40 N/C). A screen for detecting electrons is positioned parallel to the y axis, at distance x = 1.84 m. What is the y component of the electron's velocity (sign included) when the electron hits the screen? PART 2) In...

A block of mass M = 10.0 kg is given an initial speed v0 = 2.10 m/s from height hi down a frictionless incline plane of angle θ = 75◦. After it reaches the bottom of the incline, it continues to slide on a horizontal surface of coeﬃcient of kinetic friction µk = 0.15. After sliding a distance d = 1.8 m along the horizontal surface, the block moves at a speed v = 7.00 m/s. Magnitude of acceleration due...

1) A projectile has the least speed at what point in its path? a) At its maximum height. b) Just before it hits the ground. c) Just after it's fired. d) After three seconds of travel. 2) The magnitude of a vector can never equal the length of one of its components. True False 3) Can a particle with a constant speed ever be accelerating? a) Yes, because acceleration and velocity are unrelated. b) No, because its speed is constant....
