Chapter 6, Problem 92A

(a)

To determine

To Complete:The problem so that it must be solved using the concept Newton’s second law.

Explanation of Solution

Introduction:

Newton's second law is law of momentum and it is stated as state the rate of change of momentum is directly proportional to force applied on the object.

To complete the problem for the conceptNewton’s second law of motion the crate must be accelerated so that the force can be calculated.

The problem will be: “A worker unloading a truck gives a 10 kg crate of oranges a push across the floor and the crate accelerated at $2{\text{ m/s}}^{\text{2}}$ . Calculate the force applied by a worker on the crate.”

Conclusion:

The problem can be like this,“worker unloading a truck gives a 10 kg crate of oranges a push across the floor and the crate accelerated at $2{\text{ m/s}}^{\text{2}}$ . Calculate the force applied by a worker on the crate.”

(b)

To determine

To Complete: the problem so that it must be solved using the concept listed below “ A worker unloading a truck gives a 10 kg create of oranges a push across the floor…”

Explanation of Solution

Introduction:

Newton's third law of motion is law of action and reaction.

Newton's third law states that to every action there is equal and opposite reaction.

To complete the problem for the concept Newton’s third law of motion the crate must be accelerated so that the force can be calculated. So, the problem will be like this “A worker unloading a truck gives a 10 kg crate of oranges a push across the floor and the crate accelerated at $2{\text{ m/s}}^{\text{2}}$ . Calculate the reaction force exerted by the floor on the crate.”

Conclusion:

The problem can be like this “A worker unloading a truck gives a 10 kg crate of oranges a push across the floor and the crate accelerated at $2{\text{ m/s}}^{\text{2}}$ . Calculate the reaction force exerted by the floor on the crate.”
