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
