Question 1: A person starts at home, walks 150 m[E] at a velocity of 12 m/s [E]. He then picked up his speed to arrived at a velocity of 16 m/s [E] in 8.0 seconds. [K: show the correct formula] A. How long does it take for him to travel the first 150 meters? [K:1, A:1] B. What is his acceleration in the last 12 seconds? [K:1, A:1] Question 2: Determine the missing quantities in the following scenarios. A. A car travels 1.3 km [E], then 4.3 km [W], finally 2.4 m [E] in 45 minutes. Determine the average speed and velocity in km/hr [K:1, A:1] B. A curling stone travels at 2.5 m/s [E], if the ice provides an acceleration of 0.30 m/s2 [W], determine the velocity in 4 second. [K:1, A:1] C. An air molecule travels at 1.85 m/s [E] hits the wall and bounced back at 1.13 m/s [W] in 0.125 seconds. Find the acceleration. [K:1, A:1] Question 3: What would be deceleration for a train if it initially is moving at 140 km/h, to stop fully in 45 seconds? (I:2, A:1) Question 4: Using the position-time graph shown below to answer the questions. x 25 225 20 15 10 5 0 n t 15 '6 $8 A. Determine the instantaneous velocity at t=4 seconds. Show the sketch of the tangent and calculation in the space above B. What is the average velocity between t=3 second and t=5 second. (I:1, C:1) (1:2) Question 5: Use the v-t diagram for an object to answer the following questions. VELOCITY v (m/s) 6 4 " 1 0 2 4 6 8 10 12 14 16 TIME t(s) A. Determine the total displacement for the 16 seconds. (1:2) B. Determine the time(-s) when the object is under uniform motion. (C:2) C. Sketch the a-t diagram in the space above.
