what is the kinetic energy of a toy truck with a mass of 0.75 kg and a velocity of 4 m/s? (formula: $ke = \frac{1}{2}mv^{2}$)\n3 j\n6 j\n12 j\n24 j
Answer
Explanation:
Step1: Identify values
$m = 0.75$ kg, $v=4$ m/s
Step2: Substitute into formula
$KE=\frac{1}{2}\times0.75\times4^{2}$ $KE = \frac{1}{2}\times0.75\times16$ $KE=0.75\times8$ $KE = 6$ J
Answer:
6 J
