Hello please make sure for ever step possible ok?
(a)
From law of energy conservation,
(1/2)*m1*v^2 + (1/2)*m2*v^2 = m2*g*d
(m1 + m2)*v^2 = 2*m2*g*d
d = (m1 + m2)*v^2 / 2*m2*g
(b)
Work done on box 2 by the rope is positive.
(c)
Work done on box 1 by the rope = KE of box 1
W = m1*v^2 / 2

Step 1 Expression for work done by the frictional force on an object is, Here, k is coefficient of kinetic friction, m is mass of object, g is gravitational acceleration, and d is displacement, Work done is path dependent parameter. In the given case, the person put the box at starting position. Hence, the displacement of the box is zero. Therefore, the work done by the person on the box 1S Zero Thus, the correct option is Concept Check 6.1...
12:3 Step 1 Expression for work done by the frictional force on an object is, Here, is coefficient of kinetic friction, mis mass of object, g is gravitational acceleration, and is displacement. Work done is path dependent parameter. In the given case, the person put the box at starting position. Hence, the displacement of the box is zero. Therefore, the work done by the person on the box is zero. Thus, the correct option is oncept Check 6.1 A person...
A mass m = 17 kg is pulled along a horizontal floor with NO friction for a distance d =6 m. Then the mass is pulled up an incline that makes an angle θ = 37° with the horizontal and has a coefficient of kinetic friction μk = 0.4. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 37° (thus on the incline it is parallel...
Suppose the surface in the example is sloped as shown in the figure, but everything else remains the same. Determine the equation for the acceleration in this case using angular momentum and torque. Let a positive acceleration represent acceleration of m2 up the surface. (Use the following as necessary: m1, m2, M, θ, and g.) A sphere of mass m1 and a block of mass m2 are connected by a light cord that passes over a pulley as shown in...
hi this is my first question multiple choose its only 4 question in the firsr part Question 1 Not yet answered Marked out of 50.00 P Flag question A box with mass m = 2 kg slides up an inclined ramp with length d = 5 m as shown in the Figure. The box starts with an initial speed v; at the bottom of the ramp. The box slows down as it slides up due to a constant friction force...
Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....
A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...
