For the quantities in figure 2 (the picture and the table , namely ; power, speed, time, wheel base, turning circle diameter, curb mass) 1. Convert the info related to the specification and performance of the 718 cayman GT4above to SI units. (note that 1 hp= note that 1 hp= 735 watt) 2. If the power = force *distance/time, measured by Watt. Define 1Watt in terms of the fundamental SI units.
For the quantities in figure 2 (the picture and the table , namely ; power, speed, time, wheel base,
turning circle diameter, curb mass)
1. Convert the info related to the specification and performance of the 718 cayman GT4above to SI
units. (note that 1 hp= note that 1 hp= 735 watt)
2. If the power = force *distance/time, measured by Watt. Define 1Watt in terms of the fundamental
SI units.
3. Identify which quantities are basic and which are derived quantities
4. Indicate which quantities are vectors and which are scalar

5. To guarantee that this car can break the latest rally records, the owner decided to make simple
calculations to check the time needed to drive the racing distance, the equation he remembers
from the old school days in the physics course when he was a student is:
Xf = Xi + V* t+0.5 a*t
Where: xf, xi are the final and initial positions relatively, v is the velocity, a is the acceleration and
t is the time. Prove to the owner that the equation he will use is dimensionally incorrect.
6. If the kinetic energy (kg.m2 /S2
) is given by the equation m x * v y calculate the values of x and y
which make the equation dimensionally correct.
7. If the vehicle velocity changes from 0-60mph in 4.2 s, Calculate the average acceleration when
starting the motion in (km /hr)
8. If the driver applies the brakes after reaching the maximum speed (189mph), to get a constant
acceleration of 4. 5m/s2
a. Max. braking distance (Assume constant acceleration)
b. Max. Stopping time (Assume constant acceleration)
c. If the driver identifies a certain hazard on the way that is 120 m away, will the driver hit the
object or not? Knowing that he was driving with the maximum speed of the car and that the
brakes were applied directly after noticing the obstacle.
9. If it usually takes you three hours to arrive to Aqaba (from Amman) using a passenger car with a
max. Speed of 100km/hr, estimate the time you need to reach to the same point if you own this
vehicle
