A body starts from rest at a constant acceleration of 5 m/s². What distance does it cover in 5 seconds_______________?
Show answer Hide answer
Answer: B. 62.5 m
Explanation
Using the kinematic equation s equals ut plus half at squared calculates distance. Initial velocity is zero since the body starts from rest in the problem statement. Multiplying half of five acceleration by twenty five squared yields sixty two point five. Kinematic equations describe the motion of bodies under constant acceleration conditions. Distance covered under constant acceleration is proportional to the square of time elapsed. Solving physics problems requires careful substitution of given values into standard formulas.
Mechanical engineers use kinematic formulas to analyze moving parts in machinery designs. Vehicle safety testing relies on these fundamental equations to calculate stopping distances. Physics calculations form the foundation of structural and mechanical engineering analysis. Thirty eight meters is an incorrect calculation result from kinematic formula errors. Ninety six meters fails to match the correct squared time acceleration calculation. Other numerical options represent mathematical calculation errors rather than sixty two point five.
