(TAKS 5, IPC TEKS 4)
1. What is the acceleration of an object that has an initial velocity of 0 m/s, a final velocity of 40 m/s, and has traveled for 20 seconds? HINT: Acceleration (a) = (vf –vi) ÷ Δt
A 2 m/s2
B 4 m/s2
C 5 m/s2
D 2 m/s

(TAKS 5, IPC TEKS 4A)
2. A commuter train that is traveling northwest covers a distance of 45 kilometers in 75 minutes. What is the train's speed in kilometers per hour? HINT: Speed (s) = distance (d) ÷ time (t)
F 18 km/h
G 24 km/h
H 32 km/h
J 36 km/h
