Equations Of Motion
A car accelerates uniformly from rest at 2 m/s². Distance in 5 s is:
Select the correct option:
Solution
25 m
Using the equation of motion for uniform acceleration: s=ut+21at2 Given:
- Initial velocity u=0 (from rest)
- Acceleration a=2 m/s2
- Time t=5 s Substituting the values: s=(0×5)+21×2×(5)2=0+25=25 m.
