Consider the 65.0 kg ice skater being pushed by two others shown in the figure.
Consider the 65.0 kg ice skater being pushed by two others shown in the figure. (a) Find the direction (in degrees) and magnitude (in N) of Ftot, the total force exerted on her by the others, given that the magnitudes F1 and F2 are 27.2 N and 18.2 N, respectively. (b) What is her initial acceleration (in m/s2) if she is initially stationary and wearing steel-bladed skates that point in the direction of Ftot? (c) What is her acceleration (in m/s2) assuming she...

An ice skater is traveling in a straight, horizontal line on the ice with a velocity of v= 7.5 m/s in the positive x-direction. The coefficient of kinetic friction between the skates and the ice is uk= 0.22. a) Write an expression for the normal force, Fn, that the ice pushes against both skates together. Assume the skater's mass is 'm'. b) Using the expression for normal force, write an expression for the skater's acceleration In the x-direction, a. c)...

330 As shown in the figure, a 25 kg block is being pulled by a force Fup along a rough incline. The coefficient of kinetic friction between the block and the incline is uk = 0.30. Keep 2 decimal places in all answers. Step 1: Start by drawing a free body diagram of the block, including all the forces exerted on the block. Label the normal force as FN, label the weight as weight. Since the type of the frictional...

Two forces are acting on a 0.150-kg hockey puck as it slides along the ice. The first force has a magnitude of 0.405 N and points 35.0° north of east. The second force has a magnitude of 0.605 N and points 55.0° north of east. If these are the only two forces acting on the puck, what will be the magnitude and direction of the puck\'s acceleration? Enter the direction as an angle measured in degrees counterclockwise from due east....

Question 6) A 50.0 kg skater arrives at the bottom of a vertical circular track at 32.0 m/s. The radius of the track is 15.0 (m). Friction is negligible. Ignore the size of the skater so the radius of her motion is the hane as the 15.0fm] radius of the track. Point C is at the top of the track. The track goes a little bit farther than point C but we don't need to figure out what happens after...

VU22475 Apply Scientific Principles to Engineering Problems Calculate the maximum deceleration of a car that is heading down a 8 slope (one that makes an angle of 8 with the horizontal). You may assume that the weight of the car is evenly distributed on all four tires and that the coefficient of static friction is involved - that is, the tires are not allowed to slip during the deceleration. The...

Just need help on the red X
A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 79.8 N at an angle of 28.0° above the horizontal. The box has a mass of 20.0 kg, and the coefficient of kinetic friction between box and floor is 0.300. (Indicate the direction with the sign of your answer.) (a) Find the acceleration of the...
