The 20-lb cart B is supported on rollers of negligible size. If a 10-lb suitcase A is thrown horizontally on it at 10 ft/s, determine the length of time that A slides relative to B, and the final velocity of A and B. The coefficient of kinetic friction between A and B is µk = 0.4.
The block has a mass of 150 kg and rests on a surface for which the coefficients of static and kinetic friction are 0.5 and 0.4, respectively. If a force F = (60t^2) N, where t is in seconds, is applied to the cable, determine the power developed ..
A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest. ... forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.
create a primary function that uses a function handle with a nested function to compute the ninimum of the function 20x^2-200x+12 over the range 0
Using the USLE, estimate the annual erosion from a 100 ha. forested watershed assuming the following: R =112 tonnes/ha/year. The forest is in fair condition with 40% cover; Average slope is 3%; The soils are clay loam in hydrologic group C.
An equal-tangent crest vertical curve has a 50 mi/h design speed. The initial grade is +3%. The high point is at station 33+37.43 and the PVT is at station 37+18.26. What is the elevation difference between the high point and the PVT?
Design an algorithm that lists all possible rearrangements of the symbols in a string of five distinct characters. (in pseudocode)
A fluid flowing in a pipe 30cm in diameter has a uniform velocity of 4m/s. The pressure at the center of the pipe is 40KPa, and the elevation of the pipe's centerline above an assumed datum is 4.5m. Compute the total energy per unit weight of the ..
A constant power of 1.5 hp is supplied to the motor while it operates with an efficiency of ε = 0.8. Determine the velocity of the 200-lb crate in 15 seconds, starting from rest. Neglect friction.
A soil borrow material in its natural state in the ground has a unit weight of 118pcf. Its natural water content is 7%. What is the dry unit weight of this material?
What are two or three quality management tools used in data collection? What types of quality management tools do you utilize to make personal or business decisions? How do you use these tools in the decision-making process?
In the construction management, there is a lot of procurement route that are necessary and suitable for the construction industry.
A lunar module weights 1500 kg on earth where g = 9.75 mps2. On the surface of the moon where g = 1.70 mps2, what will be the force in Newtons required to accelerate the module at 10 mps2?
