P05.01
A 2000. kg truck travels in the +î direction at constant speed 10.00 ". Over the
course of 1.500 min, the driver applies the brakes to provide a constant force
that reduces the speed to 2.00 ". The driver then releases the brakes and the
truck continues at this speed thereafter.
For this activity, where appropriate the calculations are separated into three parts: scalar magnitude,
significant figures, and direction. Report the magnitudes as proper scalars - if you need to denote
something as being in a negative direction you will use the direction questions to do so (eg. the vector
v = 4.00 (-9) would be reported as 4.00 for the magnitude and the direction choice would be -ŷ, not
as -4.00 for the magnitude with +ŷ for the direction).
1) Calculate the linear momentum of the truck before the brakes are applied.
What is its magnitude? Enter the numerical magnitude in standard units but do
not include the unit in the answer field.
