A 100 g spring with a spring constant of 250 Mm is placed on a ramp that makes an angle of 40 with the horizontal. One end of the spring is hooked over the end of the ramp and then the spring is pulled backward. The spring is stretched 15 cm and then released. If the end of the ramp is 1.5 m above the floor, determine: (a) the velocity of the spring as it leaves the ramp. {7.5 mfs} Hint: The spring must possess the same amount of energy when it is stretched and then released. Note: Make sure to include a list of all known values! (b) the distance that the spring will travel horizontally (i.e. the range). {7.1 m} Hint: This is now a traditional projectile motion problem. Remember that "t" is the common factor. Note: Make sure to break your solution into two parts - vertical and horizontal - and to include a list of known values
