You can't figure "acceleration" from this information. Maybe you meant "Deceleration"? Ask again.
the magnitude of the skydivers acceleration is zero as he is decelerating by opening his parachute!
(change in velocity)/(change in time)=avg. acceleration (-30 m/s)/(15s)= -2 m/s2
If the 0.75 refers to seconds, then his acceleration is -66.66... (repeating) metres per second^2.
80 m/s2 up
80 m/s 2 up
-5 m/s² (APEX)
If your speed slows down, yYou will have negative acceleration or deceleration.
When an object slows down it is still accelerating.
the magnitude of the skydivers acceleration is zero as he is decelerating by opening his parachute!
Retardation or negative acceleration or deceleration.
-2 m/s^2
(change in velocity)/(change in time)=avg. acceleration (-30 m/s)/(15s)= -2 m/s2
If the 0.75 refers to seconds, then his acceleration is -66.66... (repeating) metres per second^2.
80 m/s2 up
66.7 m/s2
Retardation or negative acceleration or deceleration.
