Concept #1: Calculating Change in Velocity from Acceleration...

Example #1: Sliding Block

FIGURE EX2.31 shows the acceleration-versus-time graph of a particle moving along the x-axis. Its initial velocity is v0x = 8.0 m/s at t 0 = 0 s. What is the particle’s velocity at t = 4.0 s?

A particle starts from rest and accelerates as shown in the figure below.(a) Determine the particle's speed att= 10.0 s.(b) Determine the particle's speed att= 20.0 s?(c) Determine the distance traveled in the first 20.0 s. (Enter your answer to one decimal places.)
