i need help ASAP Chapter 06, Problem 53 Starting from rest, a 98-kg firefighter slides down...
Starting from rest, a 93-kg firefighter slides down a fire pole. The average frictional force everted on him by the pole has a magnitude of 810 N, and his speed at the bottom of the pole is 3.6 m/s. How far did he slide down the pole?
Starting from rest, a 90-kg firefighter slides down a fire pole. The average frictional force exerted on him by the pole has a magnitude of 805 N, and his speed at the bottom of the pole is 3.1 m/s. How far did he slide down the pole?
The alarm at a fire station rings and a 81-kg fireman, starting from rest, slides down a pole to the floor below (a distance of 4.5 m). Just before landing, his speed is 1.3 m/s. What is the magnitude of the kinetic frictional force exerted on the fireman as he slides down the pole?
The alarm at a fire station rings and a 94-kg fireman, starting from rest, slides down a pole to the floor below (a distance of 4.5 m). Just before landing, his speed is 1.3 m/s. What is the magnitude of the kinetic frictional force exerted on the fireman as he slides down the pole?
A firefighter who weighs 192 lb slides down an infinitely long fire pole that exerts a frictional resistive force with magnitude proportional to her speed, with constant of proportionality k. Find k, given that her terminal velocity is -16 ft/s, and then find her velocity v as a function of t. Assume that she starts from rest.
A student, starting from rest, slides down a water slide. On the way down, a kinetic frictional force (a nonconservative force) acts on her. The student has a mass of 81 kg, and the height of the water slide is 11.7 m. If the kinetic frictional force does -6.7 × 103 J of work, how fast is the student going at the bottom of the slide?
A student, starting from rest, slides down a water slide. On the way down, a kinetic frictional force (a nonconservative force) acts on her. The student has a mass of 81.0 kg, and the height of the water slide is 10.9 m. If the kinetic frictional force does -7.70 × 103 J of work, how fast is the student going at the bottom of the slide?
4. A student, starting from rest, slides down a water slide. On the way down, a kinetic frictional force "A non-conservative force" acts on her. The student has a mass of 76 kg, and the height of the water slide is 15.0 m. If the kinetic frictional force does - 6.2 x 10 J of work, How fast is the student going at the bottom of the slide?
A student, starting from rest,slides down a water slide. On the way down, a kinetic frictionalforce (a nonconservative force) acts on her. Thestudent has a mass of 69.0 kg, and the height of the water slide is11.3 m. If the kinetic frictional force does -5.60 103 J of work, how fast is the student going atthe bottom of the slide?
Problem 4 A child on a sled slides (starting from rest) down an icy slope that makes an angle of 15 with the horizontal. After sliding 20 m down the slope, the child enters a flat, slushy region, where she slides for 2.0s with a constant negative acceleration of -1.5 m/s with respect to her direction of motion. She then slides up another icy slope that makes a 20 angle with the horizontal. (a) How fast was the child going...
