Answer:
In free fall, mass is not relevant and there's no air resistance, so the acceleration the object is experimenting will be equal to the gravity exerted. If the object is falling on our planet, the value of gravity is approximately 9.81ms2 .
Animals don't make Their own food. they instead depend on the food made by plants. hence no need for chloroplasts
Answer:
Yes
Explanation:
When an object has more mass it takes more gravity to keep it down therefore producing friction which in return reduces the amount of kinetic energy created. A change in an object's speed has an greater effect on its kinetic energy. than a change in its mass has, because kinetic energy is proportional to.
Answer:
The acceleration of the object is -69.78 m/s²
Explanation:
Given;
postion of the particle:

The velocity of the particle is calculated as the change in the position of the particle with time;

Acceleration is the change in velocity with time;
