Crath Course QUESTION a rocket, on an unknown planct, launches straight upward. Starting from rest, the rocket accelerates uniformly until it reaches 25 m/s then maintains that velocity until its boosters shut off. It eventually falls back to the planet. QUESTION, ASSUME: • Starting at t = 0, the rocket accelerates, uniformly, upwards a total distance of 10 m, where it reaches an instantaneous velocity of 25 m's • The moment it reaches an instantancous velocity of 25 m/s, it travels 30 m upward at a constant speed, then the engines cut off. • The moment the engines cut off: the rocket is in free fall • From the time it initially launches (t- 0) to the time it lands back on the planet is 12 s • The acceleration due to gravity is constant on this planet. HOWEVER you may not assume g = 10 m/s • Air resistance is negligible QUESTION, DETERMINE: • The acceleration due to gravity on this planet

Concept explainers

Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.
