Aspeedboat moves on a lake with initial velocity vector v1,x = 8.57 m/s and v1,y = -2.61 m/s, then accelerates for 6.67 seconds at an average acceleration of aav, x = -0.105 m/s2 and aav, y = 0.101 m/s2. what are the components of the speedboat\'s final velocity, v2,x and v2,y?
find the speedboat's final speed?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
