Given:
The mass of the truck is m1 = 3162 kg
The speed of the truck is v1i = 12 m/s in East
The mass of the parked car is m2 = 510 kg
The speed of car is v2i = 0 m/s
The speed of car after collision is v2f = 24 m/s in East
To find the speed of the truck after collision.
Explanation:
The final velocity of the truck will be

Thus, the speed of the truck after collision is 8.129 m/s
The hierarchy of need was developed by Maslow. The pyramid is a motivational theory in psychology that argues that people is seeking to meet successively higher needs. The base of the pyramid is for the physiological needs to safety, belongingness, esteem, and finaly self-actualization.
Answer:
what is the question please?
Increases
Explanation:
Energy increases the speed of the particles in a substance. When energy is added to a substance they gain more kinetic to move.
- When energy is added to solid, the particles begins to vibrate about their fixed point.
- They reach a point where they break lose and the ordered structure of a typical solid collapses.
- They begin to move about freely and flow as in a liquid.
- When enough energy is added, they break their intermolecular attractions and becomes gaseous.
- An increase in energy increases the kinetic energy of the particles of a substance.
- The reverse is the case when energy is removed.
