Question

Transcribed Image Text:A 0.500-kg block sits on a rough surface connected to a 0.350-kg hanging mass by a string which runs over a massless,
frictionless pulley. The coefficients of static and kinetic friction between the block and incline are 0.60 and 0.20,
respectively.
a) On paper, show that the block will slide.
b) On paper, show your work to determine the acceleration of the system and the tension in the string.
c) Using the concept of inertia explain in the text editor why the string is less taut when the system is accelerating.
d) If the system starts from rest and moves 0.5 m, determine the following for the hanging mass. Show your work on
paper.
• Work of gravity
• Work of tension
• Net work
• Change in kinetic energy
• final speed

- (Physics Problem) Please show work neatly and box answer. Thanksarrow_forwardFundamental.7 deals with the equation of motion. The use of the equation of motion to solve this problem is mandatory. Solution using other approaches (conservation of energy ...) will be automatically considered false. For the problem related to Fundamental.7 sketches of the system showing: • the respective velocity and acceleration and the frame of reference considered • the forces acting on the system of considered, in other words, a free body diagram (FBD) are mandatory. Their absences will automatically make the problem false. B 0 r C The pendulum bob B has a weight of 6lb and is released from rest in the position shown, =0°.

- For the given mass and pulley system below, draw a diagram of the forces on the system, determine the total force and acceleration on each mass. Assume g = 10 m/s2, no friction or air resistance. Remember that F = ma, force and acceleration are vectors. The large mass is 60kg and the smaller one is 25kg.3)arrow_forwardshow work along with a free body diagramarrow_forwardA cat massing 4 kg jumps off a table from a height of 1.3 m above the ground and lands on a cushion that is 40 cm thick.
