What is the acceleration of a van that starts from rest and attains a speed of 20 ms1 in 25 s?
Options:
A .  2 ms−2
B .  0.8 ms−2
C .  7.5 ms−2
D .  4 ms−2
Answer: Option B
:
B
Given:
Initial velocity,u=0ms1
Final velocity, v=20ms1
Time, t=25s
From the first equation of motion,
v=u+at,
20=0+a×25
a=2025=0.8ms2
