Jenny's acceleration was negative during the intervals of time when her speed was decreasing.
That's really all we can tell, because you really haven't given us any information except her name.
Negative acceleration refers to times when Jenny was slowing down in her motion. Exact intervals cannot be given without further information on her motion timeline or graphical representation.
The periods during which Jenny was negatively accelerating would be the time intervals during her motion when her speed was decreasing. In a physics context, negative acceleration (or deceleration) means that the object (in this case, Jenny) is slowing down. For instance, if Jenny was running and began to slow down, the period from when she began slowing to when she stopped would be an interval of negative acceleration. However, without specific timelines or a graphical description of Jenny's motion, it's impossible to determine the exact intervals of negative acceleration.

Answer:
Inertia is the tendency or ability of a body to remain at rest or in uniform motion along a straight line in the absence of any external force. It is the reluctance a body displays when agitated or encountered by an external.
By the law of inertia, an object will always remain in its position of rest or state of uniform motion along a straight line until it is engaged with an external force.
To put it in other words;
When an object is at rest, it will want to remain at rest. If it becomes engaged with an external force it will display some reluctance before it changes its mechanical state.
Similarly, when an object is in uniform motion, it will want to continue with the motion. If an external force then interrupts it, it will also display some reluctance. This reluctance is in the form of it wanting to continue its motion irrespective of the force.
So therefore if I am moving fast on a skateboard and suddenly I become interrupted with a force, by the law of inertia my tendency is to continue the motion and this makes me exhibit reluctance in responding to the force. This reluctance will then make me to topple over and fall off if there is nothing to quickly hold unto. The more massive I am, the greater the effect of the topple. The inertia of an object is proportional to its mass.
Answer:
Total momentum is conserved
Explanation:
Conservation of Momentum
The momentum is a physical magnitude that measures the product of the object's velocity by its mass. The total momentum of a system is the sum of all its components' individual momentums. The two-bear system starts with a total moment of
When both bears stick together, the total mass is 20 kg, and the new momentum is
We have assumed both bears move to the right after the collision. In this situation, the total momentum is conserved
(b) How far away from the dart board is the dart released?
Trees, waters and other natures protect our mother earth from direct heat of ultraviolet rays of sunlight, when these are gone, it will result to too much heat and even damage to our environment.
Answer:
idk
Explanation:
Answer:
2r
Explanation:
As we know that
The displacement is the total distance measured between the initial or start and final or destination point
If particle cover half path of the circle, the displacement can easily find out by considering the distance between the start and destination point
We attached the diagram for better understanding
As per the diagram.
The displacement after half-circle is
AB = OA + OB
= r + r
= 2r
