A stone falls from rest how fast is it falling after 10 seconds?
Speed = (acceleration) times (time)Acceleration = gravity = 9.8 meters (32.2 feet) per second2Speed = 10g = 98 meters (322 feet) per second
If the speed of an object changes from 121 meters per second to 98 meters per second during a time interval of 12 seconds what is the acceleration of the object?
Acceleration = change in velocity/time a = (v - u) /t where a= acceleration, v= velocity, u= initial velocity & t= time. u = 121 m/s v = 98 m/s t = 12 m/s a = (98 - 121) /12 a = -23/12 a = -1.91667 m/s2
If the speed of an object changes from 121 ms to 98 ms during a time interval of 12s what is the acceleration of the object?
Average acceleration during the time interval = (change on speed) / (time for the change) =(98 - 121) / (12) = -23/12 = negative (1 and 11/12) meters per second2
If the speed of an object changes from 121 minutes per second to 98 minutes per second during a time interval of 12 seconds what is the acceleration of the object?
b. -1.92 m/s2Minutes per second is not a unit of velocity. If the question meant meters per second, the answer is correct.
What is the velocity of the ball when it left the bat if it was hit at a 45 degree angle and just cleared the outfield fence 98 meters away?
30.990 metres/sec

Speed = (acceleration) times (time)Acceleration = gravity = 9.8 meters (32.2 feet) per second2Speed = 10g = 98 meters (322 feet) per second
What is the maximum acceleration that a human can withstand?
The maximum acceleration that a human can withstand without injury is around 9-10 g's, which is equivalent to 88-98 meters per second squared.
Gravity causes all falling objects to accelerate at a rate of 98 meters per seconds?
The acceleration due to gravity is 9.8 meters per second squared, not 98. This means that an object in free fall will increase its speed by 9.8 m/s every second.

What is the maximum amount of acceleration that the human body can withstand?
The maximum amount of acceleration that the human body can withstand without injury is around 9-10 g's, which is equivalent to 88-98 meters per second squared.

The acceleration of gravity means that for each second that passes falling objects move 98 meters?
No, that's not correct.The acceleration of gravity means that for each second that passes, falling objects fallat a speed that's 9.8 meters per second fasterthan it was one second earlier.
You weigh yourself when you are in a motionless elevator You weigh 100 lbs The elevator starts to move and you weigh 90lbs What is the acceleration of the elevator?
The difference in weight is due to the acceleration of the elevator. Using the formula F = ma, where F is the force (weight), m is the mass, and a is the acceleration, we can calculate the acceleration to be approximately 1.02 m/s^2.
A rock falls of a bridge that is 98 meters high How fast will the rock be traveling when it hits the water?
The speed at which the rock hits the water will be approximately 44 meters per second. This can be calculated using the formula for free fall: v = sqrt(2gh), where v is the final velocity, g is the acceleration due to gravity (9.8 m/s^2) and h is the height of the bridge (98 meters).
Ten second after starting from rest a freely falling object will have the speed of about?
98 m/s, assuming the acceleration due to gravity is 9.8 m/s^2.

30.990 metres/sec
