Question 3 of 12 - /1 View Policies Current Attempt in Progress The brakes of a truck cause it to slow down by applying a retarding force of 3350 N to the truck over a distance of 927 m. What is the work done by this force on the truck? Number i UnitsQuestion 4 of 12 - /1 WH - View Policies Current Attempt in Progress A 18-kg sled is being pulled along the horizontal snow-covered ground by a horizontal force of 29 N. Starting from rest, the sled attains a speed of 2.8 m/s in 9.4 m. Find the coefficient of kinetic friction between the runners of the sled and the snow. Number i UnitsQuestion 5 of 12 - /1 IE View Policies Current Attempt in Progress An asteroid is moving along a straight line. A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 5.8x 10# kg, and the force causes its speed to change from 7900 to 5700m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 2.2x 10 m determine the magnitude of the force. (a) Work = (b) F =Question 6 of 12 - /1 WH - E View Policies Current Attempt in Progress Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 128 kg. Under the influence of a drive force of 205 N, it is moving at a constant velocity whose magnitude is 4.53 m/s. The drive force is then shut off. Find (a) the distance in which the snowmobile coasts to a halt and (b) the time required to do so. (a) s= i (b) t= iQuestion 9 of 'l 2 .' 1 E View Policies Current Attempt in Progress A small lead ball, attached to a Loo-m rope, is being whirled in a circle that lies in the vertical plane. The ball is whirled at a constant rate of three revolutions per second and is released on the upward part ofthe circular motion when it is 1.9 m above the ground. The ball travels straight upward. In the absence of air resistance, towhat maximum height above the ground does the ball rise? a v Question 12 of 12
