If a car is moving 42 meters per second after 6 sectons, the average acceletion is 7 meters per second per second. It is an average, given two points of data, and it is not the instantaneous acceleration at any point in time.

Average acceleration during a time interval = (change in speed) divided by (time for the change) =(25) / (5) = 5 meters per second2
I assume the object starts from rest. The speed will be 16*3 which is 48m/s
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
v = u + at where u = starting velocity, v = final velocity, a = acceleration, t = time. Here u = 0 so v = at ie a = v/t Now, v = 5 m/s (what is mk?) and t = 5 s So a = (5 m/s) / 5 s = 1 m/s2

It is accelerating at 1.2m/s per second.
The average acceleration is given by the expression a ∆v/∆t (15 m/s)/5s 3m/s2 where a is acceleration, v is velocity, and t is time. ∆ (final-initial) value.
Average acceleration during a time interval = (change in speed) divided by (time for the change) =(25) / (5) = 5 meters per second2
It slows to a rest and then starts moving in the opposite direction at constant acceleration in that direction.

I assume the object starts from rest. The speed will be 16*3 which is 48m/s
the acceleration is increasing speed Acceleration = velocity change / time velocity change = 0 to 25 mm/hr = 25 mm/hr time = 5 seconds therefore acceleration = 25/5 mm/hr per second = 5 mm per hour per second.
Yes, an object with constant negative acceleration can change the direction in which it is moving. Negative acceleration means that the object is slowing down, so if its initial velocity is in one direction, the acceleration can eventually cause it to come to a stop and then start moving in the opposite direction.
The acceleration of the body can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Since the body starts from rest, the initial velocity is 0 m/s. The distance traveled is 87.5 m in 5 seconds, so the final velocity can be calculated using the formula: final velocity = distance / time. Plugging in the values, we get final velocity = 87.5 m / 5 s = 17.5 m/s. Now, using the acceleration formula, we get: acceleration = (17.5 m/s - 0 m/s) / 5s = 3.5 m/sĀ².
To determine the speed of the box after 10 seconds, we need to use the formula for acceleration: ( a = F / m ), where ( a ) is acceleration, ( F ) is the force, and ( m ) is the mass. Given that the force is constant and the box starts from rest, we can further use the equation for speed ( v = a * t ), where ( t ) is time. Calculate the acceleration using the force and mass, then use that acceleration to calculate the final speed after 10 seconds.
A car speeding up from a stop sign is a real life example of acceleration. As the driver presses on the gas pedal, the car's velocity increases over time, showing acceleration.
