what is the kinetic energy of a toy truck with a mass of 0.75 kg and a velocity of 4 m/s? (formula: $ke = \\frac{1}{2}mv^2$)\n○ 3 j\n○ 6 j\n○ 12 j\n○ 24 j

Answer

Explanation:

Step1: Identify given values

Mass ( m = 0.75 , \text{kg} ), velocity ( v = 4 , \text{m/s} ), formula ( KE=\frac{1}{2}mv^2 ).

Step2: Substitute values into formula

( KE=\frac{1}{2} \times 0.75 \times (4)^2 )

Step3: Calculate ( v^2 )

( 4^2 = 16 )

Step4: Multiply step by step

( \frac{1}{2} \times 0.75 = 0.375 ), then ( 0.375 \times 16 = 6 )

Answer:

6 J
