Answer:
Speed of the wreck after the collision is 65 km/h
Explanation:
When a car hits truck and sticks together, the collision would be totally inelastic. Since the both the vehicles locked together, they have the same final velocity.
Mass of car 
Mass of truck 
Initial speed of the car 
Initial speed of the truck 
The final velocity of the wreck will be
since final speed are same, 
The first step of the scientific method is to MAKE OBSERVATIONS
I think it is diamagnetic don't quught me thoi
Iron is the solvent and carbon is the solute.
The two additional forces that act on the ball as it travels between the pitcher and the home plate are air resistance and gravity.
<h3>What are the forces that affect object in motion;</h3>
- Air resistance: this is the force that oppose the motion of an object in air due to frictional force
- Gravity: this is the force due to weight of the object and acts downwards.
The two additional forces that act on the ball as it travels between the pitcher and the home plate include:
- Air resistance and
- Gravitational force
<h3>How the forces affect the motion of the ball</h3>
- Air resistance oppose the motion of the ball as it travels in air.
- Gravity is the force due to weight of the ball and acts downwards.
