A body falls down from rest. What is i displacement in 1s? (g=10 m/s²)

AZero

B20 m

C10 m

D5 m

Answer:

D. 5 m

Read Explanation:

The displacement of a body under gravity can be calculated using the equation of motion:

Equation of Motion:

s = ut + (1/2)gt²

where:

  • s is the displacement

  • u is the initial velocity (0 m/s, since the body falls from rest)

  • t is the time (1 s)

  • g is the acceleration due to gravity (10 m/s²)

Calculation:

Substituting the values into the equation:

s = 0 × 1 + (1/2) × 10 × 1²
= 0 + 5
= 5 m
