Vector u :
u = 6 i - 3 j
The magnitude of vector u :
| u | =
Answer:
The magnitude of vector u is 3√5.
Thermal- transfer of heat thru space
Radiation- the average amount of energy of motion in the molecules of a substance

Answer:2.103 m/s
Explanation:
Given
mass of sports car
mass of SUV
Suppose u is the velocity if sports car before collision
Conserving momentum we get
After collision the combined mass drag 2.8 m and finally stops
From work energy theorem work done by friction is equal to change in kinetic energy of the combined mass system
where
Initial velocity
