A 125.0 kg box is pushed by a horizontal force F at constant speed up a frictionless ramp which makes an angle of 25.0 deg with the horizontal Find the magnitude of the applied force F?
its really easy
Does an object's velocity remain constant when its speed and velocity do not change?
Reading the question carefully, I can state categorically, withoutthe slightest fear of contradiction, that YES, the object's velocityremains constant when its velocity does not change.
A 1500 N crate is being pushed across a level floor at a constant speed. What will be the acceleration of the crate?
0 since the speed is constant
What does Centrifugal forces increases with?
This is centripetal force Fc = mv2/r, so an increase of mass or velocity and a decrease of radius will increase the centripetal force (or send the object flying away quite fast).. Centrifugal force is only a feeling of being pushed to the outside, based on human perception
When the gas pedal is pushed what force causes the change in velocity?
The Increase in Gas and Air fed into the engine cause it to produce more energy. This in turn increases its RPM, and the driving wheels rotate faster...increasing the car's Velocity.
A science book is being pushed across a table Can the book have a constant speed and a changing velocity?
It can have a constant speed, and a changing velocity, but it cannot have the two at the same time. Remember: Velocity = speed with a directional component.

Why are fly overs built at an incline?
The bridge is under compression, that means that weight created by the passage of traffic is pushed outwards to the abutments
Why does your Honda seat belt release not work on a on incline?
It uses an inertia latch to lock the seatbelt in a sudden stop. On a steep incline the latch is locking due to the fact that the inertia latch is pushed forward enough to lock. This is normal.

0 since the speed is constant
What is the secret of a barrel rolling uphill?
the barrel could have one side weighted on the inside and then pushed up a slight incline so that it traveled up a slightly inclined hill.
Real life example of second law of motion?
Constant velocity is the Newton's first law. A real life example is Sunlight, an example of constant velocity, light traveling at the constant speed of light.. On earth, an ice skater gliding or a hockey puck sliding on ice is a close example of nearly constant velocity. A stable oil drilling platform is close to zero constant velocity.
If a boy m 25 kg at rest on skates is pushed by another boy who exerts a force of 500 N on him and if the first boy's final velocity is 20 msec what was the contact time?
We'll make the assumption that the boy being pushed is wearing skates that allow frictionless translation.Step 1:Calculate the acceleration (a) that would result by a 25kg mass being acted upon by a 500N force (f).f = maa = f/m = 500N/25kg = 20m/sec2Step 2:Calculate the contact time (t).We know the initial velocity (V0) is zero.We know the final velocity (Vf) is 20m/sec.From Step 1, we have determined the acceleration (a) to be 20m/sec2Vf = V0 + atat = Vf - V0t = (Vf - V0)/a = (20m/sec - 0m/sec)/(20m/sec2) = 1 secClear as mud?

What is newtons first law of motion and what does it state?
The first law deals with forces and changes in velocity. For just a moment, let us imagine that you can apply only one force to an object. That is, you could choose push the object to the right or you could choose to push it to the left, but not to the left and right at the same time, and also not up and to the right at the same time, and so on. Under these conditions the first law says that if an object is not pushed or pulled upon, its velocity will naturally remain constant. This means that if an object is moving along, untouched by a force of any kind, it will continue to move along in a perfectly straight line at a constant speed.
