Greg is in a car at the top of a roller-coaster ride. The distance, d, of the car from the ground as the car descends is determi
1 answer:
The equation 
describes the relationship of he distance traveled and the time elapsed as one object travels a specified distance. This means that when t is 2 then d is 80. You know that a car is still in the air when the distance is a positive number and zero. The equation only holds true when t is at 0 to 3.

Explanation:
Since momentum is given by:
Therefore momentum is a vector quantity in the direction of velocity.
- Inelastic collision is the type of collision in which the masses combine after collision and start moving in the direction of the greater momentum but here in this case we have the momentum equal and opposite in direction.
<u>This case can be described mathematically as:</u>
since the mass and velocity are equal:
net momentum:
