A basketball player can leap upward .5m what is the initial velocity at the start of the leap?
You can answer this question using the following kinematics equation:v2 = vi2 +2a(x-xi)where v is the final velocity, vi is the initial velocity, a is the acceleration, x is the final position and xi is the initial position.The displacement (x-xi) is given as 0.5m, and since the person is jumping upwards, the acceleration (a) is the acceleration due to gravity, or 9.8 m/s2. The acceleration is negative because it is pointing towards the earth, opposite the direction of her jump. The final velocity (v) is 0, since it is being considered at the peak of the jump. Using this information, solve for vi.v2 = vi2 +2a(x-xi)0 = vi2 + 2(-9.8)(0.5)0 = vi2 + (-9.8)9.8 = vi2sqrt(9.8) = sqrt(vi2)3 m/s = vi
Is it possible to have a changing velocity and a constant speed?
Yes, the velocity of a constantly (or not constantly) accelerated object will vary. Velocity is distance per unit time with a vector. It's speed (distance per unit of time) in a given direction. Under constant acceleration, the velocity is changing at a constant rate. But the velocity is changing. It is varying. The object could be speeding up or it could be slowing down. Or it could be changing direction. Any of these change velocity. An object that is experiencing constant acceleration will have its velocity varying. Why wouldn't it have?
What is the difference between phototropism and geotropism?
Phototropism - towards light. Think plants, flowers, leaves. They generally turn towards light.Geotropism - towards the earth. Go figure.Hydrotropism - towards water or towards moisture.
How Can a body moving with certain velocity in the direction of east have acceleration in the direction of west?
velocity is a vector quantity and also acceleration is a vector quantity. Suppose my automobile is travelling in north direction and I apply brakes to it then until the automobile stops it will move in north direction while the acceleration will act in south direction as brakes are applied.
Is tropism the movement of a plant towards or away from a stimulus?
Towards. As in, phototropism. The tendency of plants to grow towards light.
How do you find initial velocity?
Impact velocity of projectile is simply its velocity at the moment of impact in reference to body it hits. For example, if a gun bullet at velocity of 800 m/s hits a car heading towards it at 20 m/s, the impact velocity would be 820 m/s.

Why velocity of flow will decrease with increase in peripheral speed of francis turbine?
the peripheral velocity of the turbine is the around velocity. the increase in the velocity of the peripheral will decrease the velocity of the flow towards the turbine
How do you drbble a basketball?
you push the basketball towards the ground and continue moving around the court.
What is the effect of changing the initial position on position time and velocity time graph?
Changing the initial position on a position vs time graph has no effect on the velocity vs time graph. Velocity is the derivative of position. This means velocity only depends on the rate of change (slope) of position. Changing the initial position of an object has no effect on the slope. Mathematically, this is equivalent to adding a constant to a function. Since the derivative of a constant is always 0, a change in initial position has no impact on the derivative. Here is an example. Say we have the position functions x(t)= 4+9t and y(t)= 27+9t. then the velocity function of x would be x'(t)=v(t)= 9 And the velocity function of y would be Y'(t)=v(t)= 9
Under what condition a body whose velocity is directed towards east has an acceleration directed west?
In circular motion an object accelerates towards the radius of the circle but its velocity is unchanged
What is the velocity of an object traveling towards earth if it has been falling for 4 seconds?
the answer to this question can be found using the following simple equation:Vf = 9.8t + ViVf = Velocity Final (m/s)Vi = Velocity Initial (m/s)t = Time (s)For your specific problem, providing the object wasn't moving at the start of the 4 second period, the answer is 39.2 meters per second.
What direction of the velocity causes a circular orbit?
The velocity in a circular orbit changes all the time. The acceleration is towards the center.
If the gravitational pull of the sun is the most then why doesn't it pull the planets towards it?
It does. The planets have velocity and inertia that keep them in orbit; but they really ARE continuously falling towards the Sun, their velocity makes them miss it constantly though!
What two pieces of information do vectors tell us?
A vector includes information about a magnitude, and a direction. For example, a velocity of "30 km/hour, towards the north-west".A vector includes information about a magnitude, and a direction.

Is basketball for boys?
Basketball is for anyone. There is a professional basketball league for both men and women, so the sport isn't geared towards a specific gender.
Does velocity of blood decreases as blood flows from the aorta towards the capillaries?
Yes
