NEET Physics Speed & Velocity MCQ Question
Type: MCQ-numerical-Hard-Class 11
A car is traveling at an initial velocity of 20 m/s. If the car stops with a constant deceleration and comes to rest after traveling a stopping distance of 34 m, what was the magnitude of the car's deceleration?
A
5.88 m/s²
B
94 m/s²
C
10.00 m/s²
D
40 m/s²
Correct Answer
Option A
Detailed Explanation
Using the equation v² = v₀² + 2ax with v = 0, v₀ = 20 m/s, and x = 34 m, solve for a: 0 = 20² + 2a(34), which gives a = -5.88 m/s². The negative sign indicates deceleration.
