Lea Haynes · Answer 1

The force exerted on the rock by the eruption is, D. 902.5 N

Explanation:

Given data,

The mass of the rock ejected by the volcano, m = 95 kg

The acceleration of the ejected rock, a 9.5 m/s²

The force acting on an object is defined as the product of the mass and its acceleration. It is given by the relation,

F = m x a

= 95 x 9.5

= 902.5 N

Hence, the force exerted on the rock by the eruption is, F = 902.5 N
