His law states that every particle is attracted to every other particle in the universe using a force that is proportional to the product of their masses <span />
Answer:
Rest
Explanation:
Rest is a change in the position of a body with respect to time relative to a reference point. The stationary state of an object or body relative to a reference position or another object is called Rest.
Taking Newton's First Law of motion into consideration, an object will remain in its state of rest or uniform motion until acted upon by an external force. This implies an object at rest is an object with zero (without) velocity and acceleration.
Answer:
If the height is in metres, the speed is 24.25m/s
Answer:
Approximately 
.
Explanation:
Assuming that there is no other force on this vehicle, the 
force from the road would be the only force on this vehicle. The net force would then be equal to this 
force. The size of the net force would be 
.
Let 
denote the mass of this vehicle and let 
denote the net force on this vehicle.
By Newton's Second Law of motion, the acceleration of this vehicle would be proportional to the net force on this vehicle. In other words, the acceleration of this vehicle, 
, would be:
.
For this vehicle, 
whereas 
. The acceleration of this vehicle would be:
.
