A 3 kg block slides down a 30 degree inclined plane with constant acceleration of 0.5 ms2 The block starts from rest at the top The length of the incline is 2 m What is the final velocity?

This is a tough question. There's so much information given that it's difficult to dig past the useless stuff and find our way to the info we actually need. Turns out we don't need the mass of the block or the angle of the incline. We can do just fine with the acceleration and distance. Average velocity = 1/2 (Vinitial + Vfinal) = 1/2 Vfinal Distance = (average velocity) times (time) time = Distance / (average velocity) = 2 x distance / Vfinal = 4 / Vfinal Distance = 1/2 a t2 = 1/2 (0.5) (4/Vfinal)2 2 = 1/4 x 16 x (1/V2final) ===> 2 V2final = 4 ===> V2final = 2 Vfinal = sqrt(2) meters/sec

Why is the ball deccelerating on an inclined plane?
The acceleration due to gravity remains constant, regardless of incline. The fact that it is on an incline does not change the fact that it will remain constant, it will only change the component of that acceleration being applied to the ball.
How did changing the slope of the incline change your velocity and acceleration value?
changing the slope of the inclined plane changes the values for velocity because of the unbalanced external force exerted on the object increases the velocity.
How did changing the slope of the incline change your velocity and acceleration values?
changing the slope of the inclined plane changes the values for velocity because of the unbalanced external force exerted on the object increases the velocity.
If mass increases and there is no friction would the acceleration of an object increase when place on an incline plane?
Yes. The acceleration is directly proportional to the objects mass.For objects with constant mass however, the acceleration will remain constant.
Is incline a verb an adjective or a noun?
Incline is both a verb and a noun. It is not an adjective. As a verb: to incline or to be inclined. To have the inclination to do something. As a noun: an incline or an inclined plane.
Does the length of an inclined plane affect final velocity. If the planes are different lengths but all the same height and ending at the same point?
(ignoring friction)yes, it does, the rate of acceleration is tied to the incline angle, so assuming the incline angle remains the same, lengthening the incline will result in a higher terminal velocity. v^2 = (u^2) + (2*a*s)if a mass falls the same vertical distance from rest, regardless of incline angle, its terminal velocity will be the same, converting potential energy (m*g*h), into kinetic energy (0.5m*v^2)
What wound your bathroom scale read if you weighted yourself on an inclined plane?
Your mass times the acceleration due to gravity times the sine of the angle of the incline
The ideal mechanical advantage for an inclined plane is equal to the length of the incline divided by the?
Ideal Mechanical Advantage for an Inclined Plane is equal to the length of the incline divided by the height of the incline.
Are you agree that your weight is equivalent to the friction force. Why?
No. On a horizontal surface the normal force is equal to weight. If you are moving at constant velocity you only overcome frictional force, which is not equal to weight. This is easier to see on an incline. At some point an object will slide at constant velocity down the incline. This is related to trig functions of the angle of incline multiplied by the weight which is always less than the weight.
What states that states that a body's change in mass is proportional to the amount of force applied to it?
Newtons second law of motion, describes the relationship between force, mass and acceleration: f = m * a , ( a = f / m ), ( m = f / a ) > Inclined plane: The force (kgf) down the incline on a body on an inclined plane is = mass (kg) * (sin (incline angle)) So if you change the mass, the force down the incline changes in proportion, the acceleration will remain the same, regardless of changes in mass.
What is the mechanical advantage of an incline plane?
MA of inclined plane:Distance moved parallel to slope / vertical distance moved:Reciprocal of sin of incline angle (from horizontal):1 / ( sin ( incline angle ) )
Is a knife an inclined plane?
If you incline it, yes.
