On April 15, 1912, the luxury cruise liner Titanic sank after running into an iceberg. A)what momentum would the 4.23 X 10^8- kg ship have imparted to the iceberg if it had hit the iceberg head on with a speed of 11.6 m/s? (Actually, the impact was a glancing blow). B) if the captain of the ship had seen the iceberg a kilometer ahead and tried to slow down, why would this have been a futile effort?

1. how to locate the image in converging(concave) mirror and diverging (convex) mirror with salt. 2. how to locate the image in a converging (convex) lens and diverging (concave) lens with salt.

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.

During a car accident, a 125kg driver is moving at 31m/s and in 1.5s is brought to rest by an inflating air bag. what is the magnitude of the change in momentum to the driver
