4.5 Draw a neat sketch of the velocity-time graph for the motion of vehicle P from the
moment the driver sees the wreck until it stops. Take the time when the driver sees
the wreck as t = 0 s.
Clearly show the values of the following on the graph:
Initial velocity of the vehicle
The time when the brakes are applied
The time when the vehicle stops

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?
