Step 1

In algebra we have numbers involving radicals and exponents. A radical expression is an expression containing square roots. An equation which contains radical expressions with variables is called radical equation.

An exponent is the expression of the form

Step 2

The radical expression and the exponents are very important parts of algebra. To find the solution of an expression or an equation we frequently use the conversion formulas of radical to exponent and vice versa .

In the given Radical form

For square root we have the index 2 , but for square root we will not mention index.

For cube root we have index 3 , and it is written as "

Hence in general "

Hence answer of the first blank is to be filled with nth root.

And the answer of the second blank is to be filled with index.

The spring of a spring gun has force constant k =400 N/m and negligible mass. The spring is compressed 6.00 cm and a ball with mass 0.0300 kg is placed in the horizontal barrel against the compressed spring.The spring is then released, and the ball is propelled out the barrel of the gun. The barrel is 6.00 cm long, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun is held so the barrel is horizontal. Calculate the speed with which the ballleaves the barrel if you can ignore friction. Calculate the speed of the ball as it leavesthe barrel if a constant resisting force of 6.00 Nacts on the ball as it moves along the barrel. For the situation in part (b), at what position along the barrel does the ball have the greatest speed?
