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) = 0
Final velocity (v) = 72 km/hr =20 m/s
Time taken for change of velocity (t) = 10 seconds
Acceleration, a = (v-u)/t = (20-0)/10 = 20/10 = 2 m/s2
What else can I help you with?
You were given a question concerning velocity how would you go about finding change in velocity?
acceleration
What is the velocity of the object 0.10 seconds after it is released?
To answer this question we would need to know the acceleration, which is not provided.
What is the formula to find the mass when they give you the acceleration and mass?
You ignore the acceleration, and just give them the mass. Now, if they give you the acceleration and the applied force, you could use m = F/a.
Give you a question about acceleration and decceleration?
IF your question accelerates towards me at 6megabytes per second then how long will it take me to answer(deccelerate) it if my current velocity is 299.996 miles per second.
What is needed to give a large boulder a larger acceleration?
To give a large boulder a larger acceleration, you would need to apply a greater force to overcome the boulder's inertia. Increasing the force applied to the boulder by pushing, pulling, or using a mechanical device capable of exerting more force would result in a larger acceleration.
What would the acceleration be if it took 10 seconds to go from 8ms to 18ms and why?
Divide the difference in speed by the time it takes. This will give you the average acceleration for that time period.
How to calculate g force from acceleration?
To calculate g-force from acceleration, divide the acceleration by the acceleration due to gravity (9.81 m/s2). This will give you the number of g-forces experienced. For example, if the acceleration is 20 m/s2, the g-force would be 20/9.81 2.04 g.
What is the acceleration of a 24 kg mass pushed by a 6N force?
Acceleration is 0.25m/s2 (A = force/mass).
How does the acceleration of the bullet compare with the acceleration of the rifle?
Both objects accelerate, however due to Newton's 2nd law the acceleration of the rifle is less due to it's higher mass. Newton's second law F = ma In your question the force (F) would be the same on both objects, but the mass (m) would be different and give a different answer for acceleration (a). This difference can be seen by looking at the effect of being on opposite sides of the rifle (ie kickback vs bullet hole)
5 question with answer in acceleration?
yes.
Do you have an example of an acceleration word problem?
give sample of word problem of acceleration
What is the acceleration of the boat for the 2 s to 4 s time interval?
To find the acceleration of the boat from 2 s to 4 s, you would need to calculate the change in velocity over that time interval and divide by the time taken. This would give you the average acceleration for that time period.
