A small block with mass 0.0425 kg slides in a vertical circle of radius 0.525 m

Explanation:

From the question we are told that

Mass of block

Radius of circle

Force  of track

Normal Force on block

Generally the equation for Velocity of block is mathematically Given by the law of conservation of energy

For initial velocity

0.660 = 0.0425 x u^2/0.525 - 0.0425 x 9.8

Generally the equation for work done is mathematically Given by

Step-by-step explanation:

f(4) = 42 + 5 =21, f(-10) = (-10)2 +5 = 105 or alternatively f: x → x2 + 5.

The phrase "y is a function of x" means that the value of y depends upon the value of x, so:

y can be written in terms of x (e.g. y = 3x ).

If f(x) = 3x, and y is a function of x (i.e. y = f(x) ), then the value of y when x is 4 is f(4), which is found by replacing x"s by 4"s .

If f(x) = 3x + 4, find f(5) and f(x + 1).

f(5) = 3(5) + 4 = 19

f(x + 1) = 3(x + 1) + 4 = 3x + 7
