Calculate the average acceleration of a car that changes speed from 0 m/s to 15 m/s in 5s?
15m/s divided by 5s = 3m/s^2
What velocity does the aircraft gain in 5s if an aircraft has a uniform acceleration of 4ms2 on take off?
The change in velocity, in this case, is equal to acceleration x time.
What is the final velocity of an object that starts at 45 mph and accelerates at a rate of -10 mphsec for 3 seconds?
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
If a ball that is freely falling has attained a velocity of 19.6 meters per second after 2 seconds. What is its velocity five seconds later?
A freely falling Ball has the acceleration of 9.8 m/s/s so after 5 seconds its velocity will be: t=5s a=9.8m/s/s v=5s * 9.8m/s/s =49 m/s
A skipper on a boat notices waves crests passing his anchor chain every 5s He estimates the distance between wave create to be 15m What is this speed?
(15 meters) / (5 seconds) = 3 meters per second
A bike starts at rest and after 5s it is moving at 5mk what is the average acceleration?
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
If a skydiver has a starting velocity of 2 meter per seconds and falls straight down with no friction what is her velocity 5 seconds later?
v = vo + gt = 2(m/s) + 9.8(m/s2) x 5s = 51(m/s)
How many 5s go into 110?
21 5s
Which is better the iPhone 5 or the iPhone 5s?
5s
5s plus 2 x 2d?
It is 5s + 4d.
6r plus 5s-5r equals?
5s-r
A car starts at rest and attains a velocity of 15 meters per second in 5 seconds what is its acceleration?
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.
