Assuming that the ball does not hit the floor within the first second of motion, which of these graphs represents the speed of the ball plotted against time?

t = 22.7 "s" WARNING: LONG-ish ANSWER What we'll essentially be calculating is the sum of three different times: the time it takes to accelerate to the given maximum speed, the time it …

May 11, 2018 · Use equation of motion v = u + at Where v = Final velocity u = Initial velocity a = Acceleration t = Time taken change velocity from u to v t = v − u a = 24.5 m/s – 14.2 m/s 2.2 …

The graph shows the variation with distance #d# of the displacement #x# of points in the medium. What is the average speed of a point in the medium during one full oscillation? A particle of …

Jan 29, 2018 · I think it is 0km"/"h. First of all, I don't think that acceleration has to do anything with this. Anyways, let's get right into the problem. Average velocity is defined by the equation: …

\mu=F_"frict"/ (mg)=4/ (2xx9.8)=0.20 The object's final velocity will be v=0 ms^-1, the initial velocity u=10 ms^-1 and the distance 25 m. We can use this to find the object's acceleration …

#"The slope of velocity-time graph gives deceleration of object."#

Please see below. Average speed is total distance covered divided by total time taken; and average accelaration is change in velocity divided by total time taken. (A) As bicycle takes 15 …

Apr 24, 2018 · The answer is the first graph: Given y^2-x^2/9 >= 1 We know that the equation: y^2-x^2/9 = 1 Is a hyperbola with a vertical transverse axis; this eliminates graphs 3 and 4 …
