Hey i am confused. So i know how to get average acceleration (delta v / delta t) and i know that instantaneous acceleration is the limit as t->0 but wouldn't that be infinity? i know that if you take the derivative of position you get velocity and...
Answer:
first...no dat wont b infinty...limit is applied as t tends to zero cz the time for intantaneous acc...

If a Cessna 172 requires 20 seconds to reach its liftoff speed of 120 km/h, what is its average acceleration? - my answer (from using my book) would be to take 120km and divide it by 20s to equal 60 km/h as its average acceleration. But of course I'm...
Answer:
120 divided by 20 is 6 not 60 But look at the units. 120 Km/hr / 20 sec = 6 Km/hr/sec It is actually...

2.11.6 (2.00) The driver of a jet-propelled car is hoping to break the world record for ground-based travel of 341 m/s. The car goes from rest to its top speed in 26.5 seconds, undergoing an average acceleration of 13.0 m/s2. Upon reaching the top speed...
Answer:
a) When accelerating from rest: speed = acceleration × time They give you the acceleration. They...

At a certain time a particle had a speed of 34 m/s in the positive x direction, and 8.1 s later its speed was 71 m/s in the opposite direction. What was the average acceleration of the particle during this 8.1 s interval? I know the average acceleration...
Answer:
If the particle's direction of travel didn't reverse, then your calculation would be correct. Since...

Hello I have some problem with finding the average acceleration for a man who is jumping on the moon, i know the data i need to find the average acceleration, but dont know how to, the data is t / s - 0.26 0.4 0.51 0.73 0.86 0.98 1.14 v / m/s - 0.72...
Answer:
The answer is much easier than you are making it. Average acceleration is just change in velocity over...

I know the answer, but not sure how to get it. Question: At an air show, a jet plane has velocity components : Vx= 695 km/h Vy= 430 km/h Time= 4.85s And.. Vx= 888 km/h Vy= 425 km/h Time= 7.32 s For this time interval, find the x component of the plane...
Answer:
velocity=(888km/h-695km/h)=193km/h then you have to change this velocity(193m/h) into m/s by multiplying...

I am doing a "Free-Fall" lab in physics and I have to find the average velocity and acceleration. I read the directions so many times and I still can not figure out how to find these values. In the lab I'm doing, we are dropping a ball on Earth...
Answer:
1) average velocity = total displacement / total time = 10.54 / 3 = 3.513 m/sec 2) and in free fall...

An artificial earth satellite has a circular orbit of radius 7.21 106 m (which means it is orbiting approximately 850 km above the surface of the earth) in an equatorial plane. The period T (the time required for one complete orbit) is 5.63 103 s (about...
Answer:
Since the acceleration is constant, the value in (c) should be the answer. (8.98 m/s² toward the...
