Sketch the following speed-time graphs:
determine the:
- acceleration of the objects
- distance travelled
1. a car travels at a steady(constant) speed of 65 km/h for 3 hours.
2. a boy runs from rest and steadily accelerates to a speed of 10 m/s within 5 seconds.
3. a motorcycle accelerates steadily from 12 m/s to 24 m/s over a period of 6 seconds.
4. car decelerates steadily from a speed of 54 km/h until it stops 6 seconds later.

For the below questions, consider a consumer that consumes two goods, x and z with the following utility function. u with bar on top space equals space x to the power of 1 third end exponent z to the power of 2 over 3 end exponent suppose initial values for income and the prices of goods x and z are y equals 90, p subscript x equals space 10, and p subscript z equals 15 respectively, then the price of good x falls to syntax error from line 1 column 89 to line 1 column 100. unexpected '\'.. what is the magnitude of the total effect
