Question
Q:- The speed of a car increases with constant acceleration for 32 hours. Its Initial Speed is 16 kilometers/hour , and total Distance travelled is 4096 kilometers
Find [1] How much is its final speed.
Find [2] How much was its acceleration
-
Step : 1
Distance Travelled= Average Speed x Time of Acceleration
4096 = Sav x 32
4096 / 32 = Sav = 128 kilometers/hour
-
Step : 2
Average Speed (when acceleration is constant)= [(Initial Speed + Final Speed) /2 ]
128 = [ (16 + S2)/2 ] = 128 kilometers/hour
128 x 2 - 16 = S2 = 240 kilometers/hour
-
Step : 3
Final Speed = Initial Speed + Acceleration x Time of Acceleration
240 = 16 + A x 32
( 240 - 16 ) / 32 = A = 7 kilometers/hour2
