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
9.8 meters/second2 x 10 seconds = 98 meters/second.
98 inches = 2.4892 meters.
98 meters = 321.52231 feet
Many things could be 98 seconds long. Possibly you mean a particular peice of music or song?
