Type: MCQ • Marks: 1
Average acceleration vector for a particle whose velocity changes from v1 = 10i^ m/s to v2 = 10j^ m/s in Δt = 2 s is:
Options
A. -5 i^ + 5 j^ m/s^2
B. 5 i^ + 5 j^ m/s^2
C. 10 i^ + 10 j^ m/s^2
D. 5 i^ - 5 j^ m/s^2
Explanation
a_avg = (v2 - v1)/Δt = (10j^ - 10i^)/2 = -5i^ + 5j^ m/s².
