A17.5 kg block is dragged over a rough, horizontal surface by a constant force of 167 n acting at an angle of 30◦ above the horizontal. the block is displaced 23.9 m, and the coefficient of kinetic friction is 0.136. the acceleration of gravity is 9.8 m/s 2 . 17.5 kg µ = 0.136 167 n 30 ◦ if the block was originally at rest, determine its final speed. answer in units of m/s.

Explanation:

As we know that the block is dragged over the surface by external force at an angle of 30 degree above the horizontal

Now we will have

now we know that net horizontal force on the block is given as

now we know that

work done by net force is equal to change in kinetic energy of the block

so we have

the inner core.

good luck: )

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
