A ship of mass 150,000 kg and speed 8 m/s strikes a stationary iceberg of mass 10 times bigger than the mass of the ship Assume that the forces exerted by the water on the ship and on the iceberg are negligible What is the resulting velocity of the iceberg if the ship and the iceberg are stuck together after the collision?​

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
