Question

A jaguar has a kinetic energy of 131J and is running at a speed of 19m/s. What is the mass of the jaguar?SHOW LESS0

Solution

The mass of the jaguar is approximately 0.725kg.

Step 1: Given kinetic energy (KE) = 131J and velocity (v) = 19m/s. Step 2: The formula for kinetic energy is KE = 0.5 * m * v^2, where m is the mass. Step 3: Substitute the given values into the formula: 131 = 0.5 * m * (19)^2. Step 4: Calculate the mass of the jaguar: 131 = 0.5 * m * 361 m = 131 / (0.5 * 361) m = 131 / 180.5 m ≈ 0.725kg
