Average acceleration over a certain time period is the difference in velocity, divided by the time. In this case, (4-2)/W.
The idea is that you should: a) Calculate the change in velocity. b) Divide this change by the time. This gives you the average acceleration over the 20 seconds, in this case.
The average rate of acceleration is (11/5) = 2.2 m/sec2 .
Positive acceleration!(:
for centripetal acceleration, a=(v2)/r where v = the tangential speed and r = radius of the circle. c = 2r * pi r= c/(2*pi) a=(v2)/(c/(2*pi)) a=(2*pi*v2)/c a=(2*3.141592...*(8.12))/200 a= 2.06 ms-2
2.8 m/s :)
4.0 s
Gravity doesn't have speed , it has acceleration. On Earth gravitational acceleration is 9.8 ms^-2. Often approximated to 10 ms^-2
