The spring constant (K) is 25 N/M, Êthe maximum velocity is Êgiven ÊbyÊ AW where ÊA is Êthe amplitude (0.32 m) and w is given by the formula (k/m)^0.5. ÊTherefore the maximum velocity is Ê2.4 m/s (0.32 x (25/0.45)^0.5).

What is the number of newtons is the gravitational force minus the number of newtons for the drag in water?
That depends how fast the object moves. However, once it falls in the water at a constant velocity, you know that the net force - which is just what the question is after - is zero.
Witch one of newtons laws states that every onject maintains constant velocity unless acted on by an unbalanced force?
I think it's the third one.
How can you increase the velocity of thre ore?
We can use Newtons 2nd law to figure this out. The formula is Force (Resultant) = Mass x Acceleration. The ores mass is constant. If you use a greater force, working out the formula, the velocity increases.
What forces work on a skydiver?
(standard air pressure and gravity)>(Constant) Force down (newtons) = mass * acceleration due to gravity>Say 70 kg skydiver @ 9.82 m/s/s = 70 * 9.82 = 687.4 newtons>Force up (newtons) = velocity 2 * drag coefficient (say 0.16 typical)>Terminal velocity (when forces balance) 687.4 = v 2 * 0.16Terminal velocity = square root (687.4 / 0.16)= 65.546 metres per second ( 147 mph) terminal velocity
When a 10 newton falling body encounters 4 newtons of air resistant the net force on the body is?
6 newtons, so it keeps accelerating. As it does, the air resistance increases until it reaches 10 newtons so then the net force is zero and then the fall continues at constant speed (the terminal velocity).
Is it true that an object in motion at a constant velocity will change its motion only if a central force acts on it?
yes it is one of newtons laws of motion

What is the only force acting on objects in freefall?
constant force down (newtons) = mass (kgs) * acceleration due to gravity (m/s/s) > increasing force up (newtons) = velocity (m/s) 2 * objects drag coefficient

6 newtons, so it keeps accelerating. As it does, the air resistance increases until it reaches 10 newtons so then the net force is zero and then the fall continues at constant speed (the terminal velocity).
Who invented velocity?
the person who discovered velocity was newton. so you should look up newtons theory on velocity.
What determines the volume of a sound?
Loudness is the subjective personal perception of the ears and brain of a listener. Perceived loudness varies from person to person and cannot be measured.You can measure the objective sound pressure or sound pressure level SPL but not the subjective loudness.
What two factors affect air resistance on a falling object?
constant force down (newtons) = mass (kg) * acceleration due to gravity ((m/s)/s) > variable force up (newtons) = velocity2 * drag coefficient > terminal velocity is where forces balance
Why an object moves with uniform speed even if two forces acting on it in opposite directions are equal?
According to Newtons 1st law of motion, a body moving with constant velocity will move with it until an external force compelled it to change its velocity or which is also known as the Inertia of motion. As two equal and opposite forces acting on it , the net external force is zero, so it will move with constant velocity.
What is the magnitude of the apparent weight of a 67kg astronaut 4400km from the center of the Earth's Moon in a space vehicle moving at constant velocity?
The force on the astronaut and the moon = 16.97 newtons (1.73 kilogram force)
