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
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.

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 happens to weight and mass of an object when the object is moved from earth to Jupiter?
The mass of an object stays the same no matter where it is, as it still has the same amount of matter in it (the definition of mass is the amount of matter in an object). However, the weight of an object changes based on the gravitational pull of the celestial body it is on. The equation W = m * g where W is the weight, m is the mass of the object, and g is the gravitational acceleration of the celestial body (which changes from body to body) shows that an object's weight would change with the planet's gravitational acceleration. For example, the gravitational acceleration is 9.8 m/s^2 on Earth, and the gravitational acceleration on Jupiter is about 25m/s^2. So let's work out the equations with a 100 kg mass. Earth: W=mg W=100kg*9.8m/s^2 W=98 kg/m/s^2 or 98 newtons Jupiter: W=mg W=100kg*25m/s^2 W=250 kg/m/s^2 or 250 newtons So, (250/98 = ~2.5) things weigh about 2.5 times more on Jupiter, but have the same mass.

What causesm 98 Toyota Camry to stall during acceleration?
A bad fuel line can cause a 98 Toyota Camry to stall during acceleration. This happens when the line can not get proper fuel to the engine.
What is the net force when the object encounters 15-N of air resistance?
if its in freefall, constant force down = mass (kg) * gravitational acceleration (about 9.8 on earth), so 100 kg body gives 100 * 9.8 = 98 newtons, subtract your 7 n = 91 n for acceleration .

Does gravity causes all falling objects to accelerate at the rate of 98?
The rate is 9.8m/sec
How high do you have to lift a 5kg box to give it 98 Jof GPE?
You would need to lift the 5kg box to a height of approximately 20 meters to give it 98 J of gravitational potential energy. This calculation is based on the formula: GPE = mgh, where m is the mass (5kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height.
