it is the downward aceeleration of the earth
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.
The calculation required is: distance divided by time = average distance per second 98 meters divided by 10 seconds = 9.8 meters per second. To calculate in commonly used kilometers per hour multiply by 3600 ( to get Hours )and divide by 1000 ( to get Kilometers) or simply use 3.6 as a factor. 9.8 meters per second times 3.6 = 35.28 kilometers per hour 9.8 meters per second times 3600 divided by 1000 = 35.28 kilometers per hour
Speed = (acceleration) times (time)Acceleration = gravity = 9.8 meters (32.2 feet) per second2Speed = 10g = 98 meters (322 feet) per second
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.
The speed of a freely falling object 10 seconds after starting from rest is approximately 98 m/s. This is because in free fall, the acceleration due to gravity is approximately 9.8 m/s^2, so after 10 seconds, the object would have reached a speed of 98 m/s.
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.
b. -1.92 m/s2Minutes per second is not a unit of velocity. If the question meant meters per second, the answer is correct.
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
98 inches = 2.4892 meters.
98 meters = 321.52231 feet
9.8 meters/second2 x 10 seconds = 98 meters/second.
Many things could be 98 seconds long. Possibly you mean a particular peice of music or song?
