A contestant in a winter games event pulls a 60.0 kg block of ice across a frozen lake with a rope over his shoulder as shown in Figure 4.29(b). The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03. (a) Calculate the minimum force F he must exert to get the block moving. .......N (b) What is its acceleration once it starts to move, if that force is maintained? .......m/s2

A student is trying to determine the critical angle (0) at which block will slide down an incline. She knows the coefficient of static friction between the incline and the block is 0.53 and the coefficient of kinetic friction is 0.44. Neglect drag. Hint: One way to solve the problem is to solve for all quantities in terms of m, e and g (but not u), then use f= uN and a trig identity to solve for 0. What is the critical angle? 13 Would the the block slide if the incline angle were 35°? cannot be det check answers I Rain to st

Your answer is partially correct. Try again. The velocity of a 2 kg particle is given by v = (2t i + 5t j) m/s, with time t in seconds. At the instant the net force on the particle has a magnitude of 44 N, what are the direction (relative to the positíve direction of the x axis) of (a) the net forće and (b) the particle's direction of travel?

In the friction experiment, if the friction block has a mass of 599 g, and it started to move at a constant speed after giving it a slight push when the mass in the hanger is 284 g (including the hanger), what is the coefficient of kinetic friction?

A contestant in a winter games event pushes a 59.0 kg block of ice across a frozen lake with a rope over his shoulder as shown in the figure. The coefficient of static friction is 0.1 and the coefficient of the the kinetic friction is 0.03. What is the minimum force (in N) he must exert to get the block moving?

It's a snowy day and you're pulling a friend along a level road on a sled. You've both been taking physics, so she asks what you think the coefficient Part A of friction between the sled and the snow is. You've been walking at a steady 1.5 m/s, and the rope pulls up on the sled at a 28 ° angle. You estimate that the mass of the sled, with your friend on it, is 58 kg and that you're pulling with a force of 72 N. What answer will you give? Submit Request Answer

A box, initially at rest, is pushed up a ramp that makes an angle of 15◦ with the horizontal as shown in the diagram. The magnitude of the pushing force is 8m newtons, where m is the mass of the box in kilograms. The force is in a direction parallel to and up the ramp. The coefficient of sliding friction between the box and the ramp is 0.25. Model the box as a particle and take the magnitude of the acceleration due to gravity to be g = 9.8 m s−2 . Express the four forces in component form in terms of unknown magnitudes where appropriate and find an expression for the resultant force acting on the box. Hence find the magnitude of the acceleration of the box, in m s−2

Figure 1 В А Three blocks, labeled A, B, and C, are connected by essentially massless strings that run over essentially massless and frictionless pulleys (as shown in Figure A above). Block A hangs straight down. The string from block A connects to block B which is sliding up and to the left along an inclined plane. The plane is inclined at an angle of theta = 0 = 52 degrees away from vertical. The coefficient of kinetic friction between block B and the plane is 0.38. Block B is connected by a different string to block C which hangs straight down. Block A has a mass of 4.1 kg. Block B has a mass of 3.7 kg. Block C has a mass of 2.5 kg. Block A is moving down and block C is moving up (the strings do not stretch). The only significant forces acting on the blocks are friction acting on block B, normal forces, tension forces, and gravity (with g = 9.81 m/s²). Calculate the %3D acceleration (in units of meters per second squared) of block A. For block A, a downward acceleration is…
