Question 1, chap 2, sect 4. part 1 of 2 10 points The velocity of a particle moving along the x axis varies in time according to the expres sion v ( t ) = ( α − β t 2 ) where α = 57 . 8 m / s, β = 4 . 5 m / s 3 , and t is in seconds. Find the average acceleration in the time interval from t = 0 to 1 . 75 s. Answer in units of m / s 2 . Question 2, chap 2, sect 4. part 2 of 2 10 points Determine the acceleration of the particle at t f = 1 . 75 s. Answer in units of m / s 2 . Question 3, chap 2, sect 7. part 1 of 3 10 points The position of a softball tossed vertically upward is described by the equation y = c 1 t − c 2 t 2 , where y is in meters, t in seconds, c 1 = 10 . 3 m / s, and c 2 = 5 . 48 m / s 2 . Find the ball’s initial speed v at t = 0 s....
