Question: With maximum acceleration, a car is brought to a complete stop in a distance of 30 m. Assuming the maximum possible acceleration does not depend on the speed of the car,
Part A: what distance is necessary to break the car to a complete stop when initially moving twice as fast?
I need help to find what distance is necessary to break the car to a complete stop.
A simple harmonic oscillator consists of a block of mass 1.40 kg attached to a spring of spring constant 165 N/m. When t = 4.00 s, the position and velocity of the block are x = +0.129 m and v = +3.415 m/s.What is the amplitude of the oscillations?
