- A zoologist pulls a block of hay towards an animal enclosure. The zoologist pulls at the angle of 27 degrees above the horizontal with a constant speed of 1 m/s. The mass of the hay is 60 kg and the coefficient of friction between the hay and the concrete is 0.29What is the value of the force F the zoologist is applying? please include a diagram using coordinate system and vectors, implied values, and known values.A 10 kg box experiences a force of 15 Newtons in the positive x-direction and 8 Newtons in the negative y-direction. What is the magnitude of the net force acting on the box? Answer in Newtons.A force of 9.4N pulls horizontally on a 1.3-kg block that slides on a rough, horizontal surface. This block is connected by a horizontal string to a second block of mass m2 = 1.90kg on the same surface. The coefficient of kinetic friction is μk = 0.23 for both blocks.A) What is the acceleration of the blocks?B) What is the tension in the string?
- Two blocks are joined by an inextensible cable as shown. If the system is released from rest, determine the velocity of block A after it has moved 2 m. Assume that the coefficient of kinetic friction between block A and the plane is 0.25 and that the pulley is weightdess and frictionless. 200 kg ㄱ 300 kg A BA man wants to move a heavy wooden crate (82 kg) across a wooden floor. However, since he is taller than the crate, he must pull it using a rope that makes an angle of 42 degrees with the horizontal. He exerts a force of 312 N as he pulls. What is the Normal Force exerted by the floor on the crate? What is the size of the Friction Force felt by the crate, if the crate moves at a constant speed in a straight line? Imagine that instead the floor is more slick, so that the crate feels a friction force half of what you calculated above. What is the crate’s acceleration?Objects with masses m₁ = 11.0 kg and m₂ = 6.0 kg are connected by a light string that passes over a frictionless pulley as in the figure below. If, when the system starts from rest, m₂ falls 1.00 m in 1.64 s, determine the coefficient of kinetic friction between m₁ and the table. 54.39 X Express the friction force in terms of the coefficient of kinetic friction. Obtain an expression for the acceleration in terms of the masses and the net force, including friction, and solve for the coefficient of kinetic friction. m1 m₂
- The diagram shows overhead views of four situations in which forces act on a block that slides on a frictionless ice surface. In which situations would it be possible for the block to move along the floor with a constant velocity? (Assume the magnitudes of the forces can be adjusted slightly). I do not understand this at all. I know gravitational force is downwards, and frictional force is opposing the pushing force, but how do I solve this?In the figure below, the coefficient of kinetic friction between the block and Inclined plane is 0.27 and angle 0 is 59°, What is the block's acceleration (magnitude and direction) assuming the following conditions? (a) It is sliding down the slope. m/s2 O down the slope O up the slope (b) It has been given an upward shove and is still sliding up the slope. m/s2 O down the slope O up the slope
