I have the following problem:
Let C= | 1 2 3 |
| 2 5 3 |
| 1 0 8 |
and D = | -40 16 a |
| b -5 -3 |
| 5 -2 -1 |
Determine the values of and and b such that D = C^-1
Do i start off by finding the determinent or the...

A PHYS1001 student uses a slingshot to project a pebble at her lecturer
(shoulder height) who is standing 40 m away. After extensive experiments she
finds that to hit the target she must aim 4.85 m above the target. Determine the
velocity of the pebble on leaving...
1)A ball is thrown upward with an initial velocity of v = 20 m/s. How long is the ball in the air? What is the greatest height of the ball? When is the ball 15 m
above the ground?
1) I have figured out
t total = 4.08s
greatest height = 20.4m
For the last bit (Finding the time when...
