x and y coordinates at t1=0 (1.1m ,3.4m)
x and y coordinates at t2=3.0s (5.3m, -0.5m)
a:components of the average velocity
sol:
x-components=(5.3m-1.1m)\3-0 =1.4m
y-components=(-0.5m-3.4m)\3-0=-1.3m
The highest velocity of a bird is approximately 200 miles per hour. This speed is reached by the peregrine falcon when it dives for hunting purposes.
It reaches terminal velocity. The speed is limited by the air resistance of the object. In most cases, terminal velocity is reached in a few seconds.
What is the air velocity of a swallow
Velocity depends on th mass of the fish. The mass isn't given. So, this question can't be solved.
African or European?
Using the definition of acceleration as change of speed / time, you basically need to know: * A time interval during which the object accelerates. * The velocity at the beginning of this time interval. * The velocity at the end of this time interval.
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
The instantaneous velocity is the limit of the average velocity, as the time interval tends to zero. If you are not familiar with limits, basically you make the time interval very small and calculate the average velocity.
Instantaneous velocity is the velocity in difference displacement in shortest time or specific time interval.
Total momentum before = total momentum afterTotal kinetic energy before = total kinetic energy afterSum of x-components of velocity before = sum of x-components of velocity after.Sum of y-components of velocity before = sum of y-components of velocity after.Sum of z-components of velocity before = sum of z-components of velocity after.
The average velocity over an time interval is the average of the instantaneous velocities for all instants over that period. Conversely, as the time interval is reduced, the average velocity comes closer and closer to the instantaneous velocity.
You subtract the initial velocity from the final velocity and divide by the time interval.
at half time intervals.
i think no
yes
No. Acceleration is (change of velocity) divided by (time interval in which it changed). If velocity doesn't change, then there is no acceleration.
Change in velocity divided by time is acceleration, but velocity divided by time has no particular significance.
