Please solve this qs for me show all steps and clear explaining
a)
work done by frictionWf = fk*AB*cos180
fk = uk*m*g
AB = 0.8 m
Wf = -0.22*1.8*9.8*0.8 = -3.10464 J
(b)
work done by gravity Wg = m*g*h = 1.8*9.8*1.4 = 24.696 J
(c)
work energy theorem
total work done = change in KE
W = 0.5*m*(v^2-u^2)
24.696 - 3.10464 = 0.5*1.4*(v^2-2.3^2)
v = 6.01 m/s

Please neatly show me how to solve these with all the correct steps and explain so I can understand the process. Thanks Part (a) Suppose the force exerted by a spring is F(x) = -kx and the spring has constant k = 325 N/m. Then suppose a wooden cube with mass m = 6 kg traveling with an initial velocity on a level surface with kinetic coefficient of friction 0.250 presses against the spring and it compresses from x =...
Can you show me all the steps please? For the figure shown below, the mass of the block is 10 kg and the coefficient of kinetic friction is 0.4 and the angle of the incline theta is 30 degree. Calculate the following: a. The value of the force F parallel to the incline require for the block to move with constant velocity. b. The work of the weight from point A to point B. c. The work of the force...
can someone help me with this, someone else tried to help me but I didn't understand what they said 4. A 3 kg block is pulled up a rough incline by a rope that exerts a 25 N force that is parallel to the incline. The angle of the incline 0 = 30° and the coefficient of friction between the block and incline u = 0.2. The block is pulled 1 m along the incline the block starts from rest....
A 0.458-kg box is placed in contact with a spring of stiffness 4.657×102 N/m. The spring is compressed 1.06×10-1 m from its unstrained length. The spring is then released, the block slides across a frictionless tabletop, and it flies through the air. The tabletop is a height of 1.400 m above the floor. What is the potential energy stored in the spring when it is compressed? What is the kinetic energy of the block just before it leaves the table...
A horizontal force of magnitude 32.1 N pushes a block of mass 3.91 kg across a floor where the coefficient of kinetic friction is 0.579. (a) How much work is done by that applied force on the block-floor system when the block slides through a displacement of 2.99 m across the floor? (b) During that displacement, the thermal energy of the block increases by 33.6 J. What is the increase in thermal energy of the floor? (c) What is the...
A horizontal force of magnitude 41.6 N pushes a block of mass 3.86 kg across a floor where the coefficient of kinetic friction is 0.591. (a) How much work is done by that applied force on the block-floor system when the block slides through a displacement of 3.38 m across the floor? (b) During that displacement, the thermal energy of the block increases by 37.8 J. What is the increase in thermal energy of the floor? (c) What is the...
A solid block of mass 60.0 kg starts from rest and slides down a rough surface with a length of 10.0 m where the coefficient of friction is uk=0.20. The surface is inclined at 40.0°. After sliding 10 meters down the incline it hits a spring with a spring constant of ks = 550.0 N/m. Draw a freebody Diagram indicating all forces. Write out and solve the force and energy equations. How high is the block above the spring at...
Please solve questions one and two with clear explanation and clear hand writing Thank you 1. For the two blocks below, draw free body diagrams for each (assume the larger box is on the floor). What force (F) must be applied to have the smaller not slide down; the coefficient of static friction is 0.6 0.5 Kg 10 Kg 2. Draw a free body diagram for each block in the system. Find the acceleration of the system and the tensions...
PLEASE SHOW ALL WORK! A wooden block with a mass of 250 g rests on a flat wooden table. The block is then pushed against a spring, compressing it. a) If the spring has a spring constant of k = 800. N/m and is compressed a distance of 15.0 cm, what is the energy stored in the spring? b) What is the speed of the block when it leaves the spring? c) The coefficient of kinetic friction of wood on...
