question 17
problem reference 6.3
a 16.0 kg sled is being pulled along the horizontal snow - covered ground by a horizontal, constant force of 24.0 n. starting from rest, the sled attains a speed of 2.00 m/s in 8.00 m.
what is the initial kinetic energy of the sled?
16.0 j
8.00 j
0 j
32.0 j

Explanation:

Step1: Recall the formula for kinetic energy

The formula for kinetic energy is \(K = \frac{1}{2}mv^{2}\), where \(m\) is the mass and \(v\) is the velocity.

Step2: Determine the initial velocity

The sled starts from rest. When an object starts from rest, its initial velocity \(v_{0}=0\ m/s\).

Step3: Calculate the initial kinetic energy

Substitute \(v = 0\ m/s\) into the kinetic - energy formula. \(K_{0}=\frac{1}{2}m\times(0)^{2}\). Since any number multiplied by \(0\) is \(0\), \(K_{0} = 0\ J\).

Answer:

\(0\ J\) (corresponding to the third option)
