Compute all parts of given question:
Question: The National Transportation Safety Bureau indicates that a person in a car crash has a reasonable chance of survival if his or her acceleration is less than 300 m/s2. Suppose that the mass of a car is 1200kg.
Part A: What magnitude force acting on the car would cause this acceleration in such a collision?
Part B: What stopping distance is needed if the initial speed before the collision is 20m/s?
Having trouble with this physics question, can you please explain with the answer.
One of Isaac Newton's insights was that the earth's gravity extended well beyond its surface even as far as the moon, How did he know that there was any force at all acting on the moon
define the magnitude of the tension in the chain.
A 1200 {\rm kg} car moving at 88 {\rm km/h} collides with a 7600{\rm kg} truck moving in the samedirection at 65 {\rm km/h} . The two stick together,continuing in their original direction at 68 {\rm km/h}. Determine the kinetic energy of the center..
