A particle starts from rest and accelerates as shown in the figure below. a (m/ $2) at (s) 5 10 15 20 (a) Determine the particle's speed at t = 10.0 s and at t = 20.0 s. t = 10.0 s 20 m/s t = 20.0 s 0 X The correct answer is not zero. m/s (b) Determine the distance traveled in the first 20.0 s. (Enter your answer to one decimal place.) 50 X Your response differs from the correct answer by more than 10%. Double check your calculations. m
