a 30 kg shopping cart is pushed at a speed of 1.5 m/s. how much kinetic energy does the shopping cart have? remember : ek = 1/2mv² ek = ? j
Answer
Explanation:
Step1: Identify values
$m = 30$ kg, $v=1.5$ m/s
Step2: Substitute into formula
$E_{K}=\frac{1}{2}mv^{2}=\frac{1}{2}\times30\times(1.5)^{2}$
Step3: Calculate result
$E_{K}=15\times2.25 = 33.75$ J
Answer:
33.75
