Question 1 (1.67 points) Saved An object moving in a straight line undergoes a constant acceleration. If the object starts from rest and moves 35.0 m in 10 seconds, determine its acceleration (mIs2). Give answer to tenths place. No unit is necessary. Your Answer: 0.35 Answer Question 2 (1.67 points) Saved The motion of a particle moving on a straight line is given by the following relationship between position (x) and time (t): x = 0.80t4 - 8.40t2 - 2.20t + 6.10 , where x is in meters and time is in seconds. The velocity (m/s) of the particle at time = 2.50 sis? Your Answer: -20.65 Answer Question 3 (1.67 points) Saved A stone is thrown vertically from the top of a tall building. The building top where the stone is thrown from is 50 m from the ground level. If it takes 4.0 s for the stone to hit the ground, determine its speed (m/s) right before it hits. (use g= 9.8 m/s2) Your Answer: 31.30 Answer Question 4 (1.67 points) Saved A boat is undergoing straight-line motion in the +xdirection with a constant acceleration ax= 0.5 m/s2. If a crewmate starts her stopwatch when the boat has a velocity vX = 12.0 m/s, what is the boat's velocity after 30 5? Your
