Newton’s first Law is law of inertia or resistance to change of motion. Objects in motion tend to stay in motion or an object at rest tends to stay at rest, unless acted on by an outside force.
Newton’s second Law is F=ma is equal to the rate of change of momentum with respect to time dp/dt. This means force is equal to mass times acceleration or F= mass*(d^2x/dt^2)
Newton’s third Law is for every force there is an equal and opposite force. Meaning if I push on the ground, the ground pushes back on me equally an opposite.
Hope this helps you understand Newton’s three laws of motion. Any questions please ask!!
Thank you!!
The base of table is "1.08856 m" far away from the ball land.
Given:
Distance travelled by ball,
Initial velocity,
Acceleration,
Constant speed,
As we know the formula,
→
By substituting the values, we get
→
→
→
→
Let,
- Horizontal distance will be "x".
- Time = t
→
Thus the solution above is right.

B they involve more than one object
Answer:
Explanation: This is done using the equation:
Because the Radius is a know value. We have the following.
Which is:
4188.7902 mm
Answer:
(a) Fₓ = 0 N
= 9.08 N
(b)
(a) Fₓ = 0 N
<u></u> = 9.08 N
(c) = 0 N
Fₓ = 9.08 N
Explanation:
The magnitude of the force will remain the same in each case, which is given as follows:
F = ma (Newton's Second Law)
where,
F = force = ?
m = mass = 4.54 kg
a = acceleration = 2 m/s²
Therefore,
F = (4.54 kg)(2 m/s²)
F = 9.08 N
Now, we come to each scenario:
(a)
Since the motion is in the vertical direction. Therefore the magnitude of the force in x-direction will be zero:
<u>Fₓ = 0 N</u>
For upward direction the force will be positive:
<u></u><u> = 9.08 N</u>
<u></u>
(b)
Since the motion is in the vertical direction. Therefore the magnitude of the force in x-direction will be zero:
<u>Fₓ = 0 N</u>
For upward direction the force will be negative:
<u></u><u> = - 9.08 N</u>
<u></u>
(c)
Since the motion is in the horizontal direction. Therefore the magnitude of the force in y-direction will be zero:
<u></u><u> = 0 N</u>
<u>Fₓ = 9.08 N</u>
