What is the Acceleration of a car that got up to 45 ms from a rest position in 3 seconds?
Velocity at time 0 sec = 0m per sec Velocity at time 3 sec = 45m per sec Acceleration is 45/3 = 15m per sec if the acceleration is uniform
State whether there can be an object with a constant acceleration but with zero velocity?
yes, if it has a constant acceleration of 0m/s2
What is the final velocity of a train that starts at rest and accelerates for 15.0 seconds at an average acceleration of 2.40 meter per second squared?
Unknown: final velocity, vfKnown:initial velocity, vi = 0m/stime, t = 15.0saverage acceleration, a = 2.40m/s2Equation:vf = vi + atSolution:vf = 0 + 2.40m/s2 x 15.0s = 36.0m/s
What is the acceleration of a cheetah that zips past you at a constant velocity of 60mi hr?
0m/s2 because the velocity is constant.
What is 0 meters per second squared?
0m/s2=0
When throw an object upward and return after 6 seconds what was its initial velocity?
Use the equation vf = vi + gt, where vf is final velocity, vi is initial velocity, g is acceleration due to gravity, and t is time.Known:vf = 0m/sg = -9.8m/s2t = 6sUnknown:viEquation:vf = vi + gtSolution:vi = vf - gtvi = 0m/s - (-9.8m/s2)(6s) = 58.8m/s = 60m/s (rounded to 1 significant figure)
What is the braking time from 1.5 to 2 seconds what is the final velocity?
To calculate the braking time from 1.5 to 2 seconds, we need to know the initial velocity and the acceleration of the object. The final velocity can be determined using the formula: final velocity = initial velocity + (acceleration * time). If we have this information, we can plug in the values to find the final velocity at 2 seconds.
If a car can go from 0 - 100 in 4 seconds what is its acceleration?
(vf-vi)/t or (100m/s - 0m/s) divide by 4seconds. Remember pemdas: parenthesis first, then divide. 100m/s2 divided by four seconds=25m/s
Can changing of velocity results in acceleration. Explain.?
Acceleration is change in velocity over time. a = vf - vi/Δt, where a is acceleration, vf is final velocity, vi is initial velocity, and Δt is the time interval. For example, a car accelerates from rest to 15m/s in 5.9s. What its acceleration? vi = 0m/s, vf = 27m/s, Δt = 5.9s, a = ? a = 27m/s - 0m/s/5.9s = 4.6m/s/s = 4.6m/s2
What does v equals 0m slash s stand for?
Velocity = 0 metres per second, ie immobility.
What is the magnitude of the acceleration of the car who is traveling along east with a constant velocity?
acceleration is the change in velocity by change in time (often meters/second/second). so, if a car was travelling 10m/s and ten seconds later, it is travelling 20m/s in the same direction, the acceleration would be (20m/s-10m/s)/10s=1m/s/s. with a constant velocity the change in velocity is zero (x m/s - x m/s)/y s=0m/s/s and acceleration is also zero.
What is the acceleration of a skateboarder traveling 12m per sec?
Acceleration is independent of speed. If the instantaneous velocity of an object is 12m/s and no other information is known, it is impossible to tell the acceleration. However, if the velocity does not change at all over a certain time interval, the acceleration over that time interval is 0m/s2. If other information is given, such as initial/final velocity, time, or displacement, then one of the the "famous five" equations may be used to determine the acceleration.
