Answer:
The first
Explanation:
Cause it will continue in motion till another force is applied
Answer:
Lightening of the table lamp
Explanation:
Energy has a different form of energy. In physics, the capacity of the form of energy is work. The energy can exist in the form of thermal, potential, kinetic, chemical and electrical, and nuclear. There are other forms of energy such as work and heat.
The energy is designated according to the nature of the objects. So that when heat transferred it has been changed into thermal. All the forms of energy are related to the motion of an object. Energy can neither destroyed or created.
When Alana moving 19km/h, a stationary object will be perceived by her as moving toward her with 19km/h velocity. If the object is not stationary(velocity isn't zero), the speed will increase by the object velocity.
the relative speed of the tennis ball=
the speed of Alana + true speed of the tennis ball
19km/h+ 11km/h= 30km/h

To start off.. add any and all the vectors acting on the same axis (x and y), making sure to pay attention to the director of the vectors. you are often able to ignore many of the forces that cancel each other out. make sure to focus on the forces that are actualy involved in how the object will move. Then you calculate the net force acting on the object in the situation
Since nothing is happening along the y-axis, you can ignore the Fg (300N)and FN (20N) forces.
FNET = Fa + Ff
= 80N + -70N
FNET = 10N
you have to make the friction a negative force
because it is pointing in the direction opposite to the applied force.
When you want to calculate the acceleration of an object, always use the net force acting on it.
you aren’t subtracting the two forces.
Instead, it’s up to you to remember that if one of the forces is pointing in one direction (like to the right), and the other force is pointing in the other direction (like to the left), you will need to make one positive and the other negative.
i don’t really know how to explain this super well. i hope this helps!!
