The average rate of acceleration is (11/5) = 2.2 m/sec2 .
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)
If he started out from "rest" (zero speed), then his average acceleration for the 5 seconds is50/5 = 10 meters per second2
You haven't mentioned the speed difference or speed gain in this question so it cannot be answered
Speed = (initial speed) plus (acceleration) x (time) = 0 + (5) x (3) = 15 meters per second.
I assume the object starts from rest. The speed will be 16*3 which is 48m/s
If you are walking or standing still you are going slower than running, if you speed up then you are accelerating.

That works out at an acceleration of 1.63 m/s2(Presumably you meant 8.15 meters per second.)You would measure how far the rock dropped in 5 seconds. Then you could work out the final speed (or acceleration) from the "equations of motion".
12 seconds.
its' about acceleration speed times 4^2

Acceleration = Change in speed/Time Time = Change in Speed/Acceleration = 65mph/20mph per s = 65/20 seconds = 3.25 seconds
Acceleration is the rate of change in velocity (speed) Thus if your speed is constant (50 miles per hour) your acceleration is zero
Acceleration = delta velocity/delta time a = 70 m/s/35 seconds = 2 m/s2 ------------
Acceleration changes the speed - usually increases it. A reduction is speed is negative acceleration , or deceleration. Acceleration can change the speed or direction (or both) of velocity.
Depends if it's standing or running. Standing it would be bhs. Running it would prob be round off
