Question 9 (1 point) A mass m1=1.5 kg rests on a 30 degree ramp with a coefficient of kinetic friction 0.40. Mass m1 is tied to another mass m with a string which runs over a frictionless pulley. Mass m is hanging above the ground. The acceleration of masses is measured 2.94 m/s2. What is m? Your Answer: units Answer Question 11 (1 point) Two masses, one is m1-2.0 kg and another one m2 =...

1. A firework (small rocket) whose shell has a mass of m 12kg was initially on the ground before being launched to a height of 100m above the ground at which point its horizontal displacement from its starting position is 17.6m. At this location its speed is 68m/s and it's at an angle relative to (and above) the horizontal of 80 as depicted in the diagram below. Once it reaches this height it goes off and its shell splits into...
