Q6. A rocket has a mass of 5000 kg and is travelling at a speed of 600m/s Calculate the rocket's kinetic energy in kilojoules . Show your working. __ Kinetic energy=ldots ldots ldots ldots ldots ldots ..kk The diagram shows a high jumper.

Answer 1

### The kinetic energy of the rocket is \(900000 \, \text{kJ}\).

Answer 2

## Step 1: Identify the formula for kinetic energy ### The problem provides the formula for calculating the kinetic energy of an object: \[\text{kinetic energy} = \frac{1}{2} \times \text{mass} \times \text{speed}^2\] ## Step 2: Substitute the given values into the formula ### The given mass of the rocket is \(5000 \, \text{kg}\) and the speed is \(600 \, \text{m/s}\). We substitute these values into the formula. ## Step 3: Calculate the kinetic energy ### Calculate the kinetic energy using the formula: \[\text{kinetic energy} = \frac{1}{2} \times 5000 \, \text{kg} \times (600 \, \text{m/s})^2\] \[\text{kinetic energy} = \frac{1}{2} \times 5000 \times 360000\] \[\text{kinetic energy} = 2500 \times 360000\] \[\text{kinetic energy} = 900000000 \, \text{J}\] ## Step 4: Convert the kinetic energy to kilojoules ### Since \(1 \, \text{kJ} = 1000 \, \text{J}\), we convert the kinetic energy from joules to kilojoules: \[\text{kinetic energy} = \frac{900000000 \, \text{J}}{1000}\] \[\text{kinetic energy} = 900000 \, \text{kJ}\]
