Speed = (acceleration) times (time)Acceleration = gravity = 9.8 meters (32.2 feet) per second2Speed = 10g = 98 meters (322 feet) per second

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

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

b. -1.92 m/s2Minutes per second is not a unit of velocity. If the question meant meters per second, the answer is correct.

30.990 metres/sec

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.

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

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.

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.

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).

98 m/s, assuming the acceleration due to gravity is 9.8 m/s^2.
