use the Impulse-Momentum theorem where (Fnewtons)(tseconds)=change in momentum change in momentum=Pf-Pi; P=mv

Acceleration is defined as a change in velocity over time. if a runner increases velocity from 2 ms to 4 ma over a period of 20 seconds what is her acceleration?
The idea is that you should: a) Calculate the change in velocity. b) Divide this change by the time. This gives you the average acceleration over the 20 seconds, in this case.
To celebrate a victory a pitcher throws her glove straight upward with an initial speed of 6.2 How long does it take for the glove to return to the pitcher?
I am assuming the initial speed is 6.2 m/s Let upward motion be positive! Gravity decreases the speed by 9.8 m/s each second Acceleration due to gravity = -9.8 m/s each second (negative because gravity accelerates objects downward) Find time to reach the top of the path! Final velocity at the top = 0 m/s Initial velocity = 6.2 m/s Final velocity = Initial velocity + acceleration * time Time - = (final velocity - initial velocity) ÷ acceleration Time = (0 - 6.2) ÷ -9.8 = 0.633 seconds (to reach top) The path is symmetrical. 0.633 seconds to reach top and 0.633 seconds to reach glove again. Total time = 12.66 seconds
What forces are difined as?
Acceleration is the change in velocity (m/s) divided by time (s), which is the same as meters divided by time in seconds squared (m/s2).
How often is the body's entire blood supply circulated?

What is the velocity of a 1000kg car if its kinetic energy is 200kJ?
KE = 1/2mass * velocity squared some conversion needed 60 kilometer per hour (1000 meters/1 kg)(1 hr/3600 seconds) = 17 meter per second ================= KE = 1/2(1000 kilograms)(17 m/s)2 = 1.4 X 105 Joules ------------------------
If a car is traveling westward with a constant velocity of 20meters per seconds what is the net external force acting on it?
It's zero
What velocity does the student have after five seconds?
Velocity increases after 5 seconds
How do you get the velocity?
Velocity is derived by dividing displacement with time in seconds
What is the velocity of the object between 20 and 40 seconds?
The velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.
What is the duration of WWE Velocity?
The duration of WWE Velocity is 2760.0 seconds.
A diver jumps from a 48ft cliff into the ocean with an initial velocity of 8 seconds when does he hit the water?
"8 seconds" is not a velocity.
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
What is venus orbital velocity?
35km/seconds
What is the formula to find time in seconds from velocity and distance?
Distance divided by velocity = time
When acceleration occurs?
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
What is the velocity of a ball thrown 20 ft in 4 seconds?
In the case of constant velocity (or speed), velocity = distance / time.
