1. What is the impulse of a 10,000 kg truck as it speed up from 13m/s to 28m/s square

To calculate the impulse of the truck, we need to use the formula:<br /><br />Impulse = Change in momentum<br /><br />The change in momentum can be calculated by subtracting the initial momentum from the final momentum.<br /><br />Given information:<br />- Mass of the truck (m) = 10,000 kg<br />- Initial velocity (v1) = 13 m/s<br />- Final velocity (v2) = 28 m/s<br /><br />Step 1: Calculate the initial momentum (p1).<br />Initial momentum (p1) = Mass × Initial velocity<br />p1 = 10,000 kg × 13 m/s<br />p1 = 130,000 kg·m/s<br /><br />Step 2: Calculate the final momentum (p2).<br />Final momentum (p2) = Mass × Final velocity<br />p2 = 10,000 kg × 28 m/s<br />p2 = 280,000 kg·m/s<br /><br />Step 3: Calculate the change in momentum (Δp).<br />Change in momentum (Δp) = Final momentum (p2) - Initial momentum (p1)<br />Δp = 280,000 kg·m/s - 130,000 kg·m/s<br />Δp = 150,000 kg·m/s<br /><br />Step 4: Calculate the impulse (J).<br />Impulse (J) = Change in momentum (Δp)<br />J = 150,000 kg·m/s<br /><br />Therefore, the impulse of the 10,000 kg truck as it speeds up from 13 m/s to 28 m/s is 150,000 kg·m/s.
