Question

a truck hits a brick wall with a force of 100000 kg.m/s2. the truck come to a stop in 0.5. calculate the impulse the truck experinced.

Answer 1

By the definiton of the impulse, we have:

$$J = F \Delta t = 100000 \dfrac{kg \cdot m}{s^2} \cdot 0.5 s = 5 \cdot 10^4 kg \cdot \dfrac{m}{s}.$$

Answer:$J = 5 \cdot 10^4 kg \cdot \dfrac{m}{s}.$
