+ | == Questions | ||
+ | |||
+ | What is the speed of the vehicle? | ||
+ | |||
+ | 216N * 1s = 216 kg m/s (Unit of momentum) | ||
+ | |||
+ | 216kg m/s / 80 kg = 2.7m/s | ||
+ | |||
+ | What is the altitude of the vehicle? | ||
+ | |||
+ | position = acceleration * time^2 / 2 (from two rounds of integration) | ||
+ | |||
+ | 2.7 * 1^2 / 2 = 1.45m | ||
