A car accelerates uniformly from rest to a speed of 72 km/h in 10 seconds. Find its acceleration and the distance traveled.
When acceleration is exactly zero, velocity remains constant, meaning the particle covers equal distances over equal intervals of time. s=v⋅tbold s equals bold v center dot bold t
The straight-line motion of a particle is governed by the acceleration equation , its velocity is and its displacement is . Calculate its velocity at Solution:
The kids' eyes widened. "So they meet 455 meters from the clocktower," the boy said, triumphant.
( v=0 ) → ( 3t^2 - 12t + 9 = 0 ) → divide 3: ( t^2 - 4t + 3 = 0 ) → ( (t-1)(t-3)=0 ) ( t = 1 , \texts ) and ( t = 3 , \texts )
v22=3(s3/23/2)+Cthe fraction with numerator v squared and denominator 2 end-fraction equals 3 open paren the fraction with numerator s raised to the 3 / 2 power and denominator 3 / 2 end-fraction close paren plus cap C
The key to solving these problems is to understand a few fundamental kinematic variables and their mathematical relationships.
