Solution & Explanation

Related Formula
a = (dv)/(dt) = -g
Core Logic

Throughout the motion, acceleration due to gravity acts downward (a = -g). Therefore, the slope of the velocity vs time curve must be constant and negative throughout.

Correct v-t graph representation for Q5 solution
Plots showing various candidates for velocity vs time curves of a projectile.

Hence, curve (C) is correct.

Pattern Recognition

Constant downward acceleration requires a straight line with a negative slope on a v-t graph.

Q30 neet_2024_05_may_morning Reaction Time and Distance
When a ruler falls vertically, 5 different persons catch it with different reaction times. (g=9.8 m s⁻²) A. Person A has reaction time of 0.20 s. B. Person B has reaction time of 0.22 s. C. Person C has reaction time of 0.18 s. D. Person D has reaction time of 0.19 s. E. Person E has reaction time of 0.21 s. What is the correct order of the distance travelled by the ruler for each person?
  • A. C > D > A > B > E
  • B. C > D > A > E > B
  • C. B > E > A > C > D
  • D. B > E > A > D > C

Solution

Related Formula
S = (1)/(2)g t²
Core Logic

Distance S ∝ t². Larger reaction time leads to greater distance fallen. Reaction times in descending order: tB (0.22s) > tE (0.21s) > tA (0.20s) > tD (0.19s) > tC (0.18s). Therefore, distances in descending order: SB > SE > SA > SD > SC.

Pattern Recognition

Free fall distance increases monotonically with reaction time.
