a = m/s/s
a = 560/1/7
a = 80m/s/s
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
Acceleration = change in velocity/change in time Acceleration = 96 miles per second - 32 miles per second/8 seconds = 8 miles per second per second or, better expressed 8 mi/s^2 ---------------
The sprinter's acceleration is 2 meters per second squared.
The change in velocity was 8 m / s. Divide that by 4 seconds and get 2 m / s2 -- sometimes stated as acceleration of 2 meters per second per second.
acceleration = change in velocity divided by timeaccel = (9-3)/3 = 6/3 = 2 meters per second per second
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
So acceleration is an increase of speed every second. The increase of speed was 9miles/sec and this was over 3 seconds. Therefore there was an acceleration of 3 miles/second every second i.e. 3m/s2
Acceleration = change in velocity/change in time Acceleration = 96 miles per second - 32 miles per second/8 seconds = 8 miles per second per second or, better expressed 8 mi/s^2 ---------------
10 feet per second squared
A rocket that travels 9000 meters in 12.12 seconds moves at 742.5742 meters/second which is approx 1660 mph
26.45ms-2
The acceleration of the body is 3 m/s²
20 miles per second / 10 seconds = 2 miles per second ^ 2
"Constant rate" implies there is no acceleration - acceleration is zero.
The sprinter's acceleration is 2 meters per second squared.
The change in velocity was 8 m / s. Divide that by 4 seconds and get 2 m / s2 -- sometimes stated as acceleration of 2 meters per second per second.
The stages of a rocket going into space: The first stage of a rocket is used to acquire the acceleration of a rocket. When the fuel of the first stage is exhausted ,it detaches from the rockets and drops off. The velocity at this stage becomes the initial velocity of the second stage .Now the second stage is ignited ,the rocket gains acceleration and it's velocity foes on increasing . The removal of the surplus mass contained in the first stage helps in attaining the higher velocity .When the fuel of the second stage is exhausted ,it too detached from the rocket .Finally at the third stage , the rocket starts off with the required velocity.
