No, that is a contradiction.
598 m
The speed of the ball during the final 2 seconds likely decreased as it experienced air resistance and friction from contact with the ground. Without additional information, we can only infer that the ball's speed reduced gradually until it came to a stop.
An example of average acceleration would be a car starting from a stop and gradually increasing its speed to 60 mph over a period of 10 seconds. The average acceleration of the car during this time would be calculated as the change in velocity divided by the time taken to achieve that change.
-2.5 m/s/s
You can't figure "acceleration" from this information. Maybe you meant "Deceleration"? Ask again.
If there is no net force on an object, the object won't accelerate.
Yes, when an object reaches its terminal speed, the acceleration becomes zero because the forces acting on the object (such as air resistance) have balanced out the force of gravity causing the object to fall at a constant speed. This constant speed is the terminal speed of the object.
If the acceleration is negative, the object's speed will decrease over time. The object will slow down until it comes to a stop, and if the negative acceleration continues, the object may eventually start moving in the opposite direction.
Acceleration = (change in speed) divided by (time for the change) = (0 - 36)/3 = -12 m/s2The acceleration of gravity is 9.8 m/s2, so the passengers are pulled forwardagainst their seat belts with a 'force' of 1.22 Gs during the screech.
Yes. You could be moving left with an acceleration to the right (decelerating) and come to a stop before you begin to move to the right.
Answer This occurs when an object istraveling in one direction but has an acceleration in the opposite direction, which means it is decreasing in speed. For a given period of time, the speed has decreased. Acceleration is the change of velocity per second. T1 = 5 seconds V1 = 100mph T2 = 10 seconds V2= 50 mph Acceleration = (V2 - V1 ) / (T2 - T1) = (50-100)/(10-5) = -10 ft/sec/sec Positive(+) acceleration means an object will be going faster over an interval of time.
