Question

question 3 of 10
a man pushes a sled across the snow, using a force of 300 n over a distance
of 2 m. what is the kinetic energy of the sled after he pushes it? assume
there is no friction.
a. 600 j
b. 300 j
c. 150 j
d. 1200 j

Explanation:

Step1: Apply the work - energy theorem

Since there is no friction, the work done by the force is equal to the change in kinetic energy. The work formula is \(W = F\times d\), where \(F\) is the force and \(d\) is the distance.

Step2: Substitute the given values

Given \(F = 300\space N\) and \(d=2\space m\). Then \(W=300\times2\).

$$W = 600\space J$$

Answer:

A. \(600\space J\)
