Average speed = (250 / 5) = 50 meters per second.
Initial speed = 0
Final speed = 100 m/s
Acceleration = (100 / 5) = 20 m/s2
===> Must be a rocket-propelled ball; its acceleration is 2G !
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Converting the initial velocity of 0 km/hr to m/s and final velocity of 60 km/hr to m/s, and plugging in the values, we get the acceleration to be 2 m/s^2.
The distance the car travels during the acceleration can be calculated using the formula: distance = (initial velocity)(time) + 0.5(acceleration)(time)^2. Plug in the values: initial velocity = 0 m/s, final velocity = 40 m/s, time = 8 s. Calculate the distance traveled during the acceleration.
The car's acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Plugging in the values gives acceleration = (118 ft/s - 91 ft/s) / 3.20 s = 8.44 ft/s^2. So, the car's acceleration is 8.44 ft/s^2.
To calculate acceleration, you need to know the initial velocity of the car and its final velocity after 6.8 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time.
To calculate acceleration between 6 and 9 seconds, you need to find the change in velocity during that time interval and then divide it by the time taken. The formula for acceleration is acceleration = (final velocity - initial velocity) / time. Plug in the velocities at 6 seconds and 9 seconds into the formula to get the acceleration.
an object uniformly accerlerates over a distance of 100 m in 20 seconds. calculate the acceleration.
So it's acceleration is 4m/s2. So at any point because it says uniformly, it will be accelerating at 4m/s2 each second

the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph

Question:A car starts from rest and accelerates uniformly. It acquires a velocity of 72 km/hr in 10 seconds. What is its acceleration?Answer:Since the car is starting fom rest, its initial velcity (u) = 0Final velocity (v) = 72 km/hr =20 m/sTime taken for change of velocity (t) = 10 secondsAcceleration, a = (v-u)/t = (20-0)/10 = 20/10 = 2 m/s2
No

No starting velocity was given, so I can't give a correct answer, but I can answer part of the question. Given an acceleration and a time through which an object accelerates, you can determine the change in velocity. Acceleration is just the change of velocity over a period of time. Since we have an acceleration of -3.1 meters per second squared, acting for two seconds, we have a change in velocity of -6.2 meters per second. Take the original velocity and subtract 6.2 meters per second to get the answer.
Acceleration on a lift can be calculated by dividing the change in velocity by the time taken. For example, if the lift starts from rest and accelerates to a velocity of 4 m/s in 2 seconds, the acceleration would be (4 m/s - 0 m/s) / 2 s = 2 m/s^2.
