Question

1. a volcano erupts on earth’s surface causing a piece of rock with a mass of 95 kg to be ejected from rest to an acceleration of 9.5 m/s². what force was exerted on the rock by the eruption? ( f = ma )

0.1 n
10.0 n
95 n
902.5 n
clear all

Explanation:

Step1: Identify given values

Mass \( m = 95 \, \text{kg} \), acceleration \( a = 9.5 \, \text{m/s}^2 \), formula \( F = ma \).

Step2: Substitute into formula

\( F = 95 \times 9.5 \)

Step3: Calculate the product

\( 95 \times 9.5 = 902.5 \, \text{N} \)

Answer:

902.5 N (corresponding to the option with 902.5 N)
