Mathematics and Scientific Calculator Review

Read the manual you got with your calculator and use this knowledge to answer the following questions. If you don't have a manual, it's your responsibility to somehow find out how to use your scientific calculator. This assignment may be collected and counted as homework. A quiz similar to this worksheet will be given shortly.
 
1.     100. = (50.0 + v)/2 (Tip: Cross Multiply)     v = ______

 
2.     19.0 = (100. - 2.00)/ t                      t = ______

3.     v²  = 8.00²  + 2.00(9.80)3.20          v = ______

 (Tip: Don't forget to take the square root at the end)

4.      F = (6.70 X 10^-11) (6.00) (1.00 X 10³ )/(.70)²
