Inchy, an inchworm, is inching along a cotton clothesline. The 5 meter long clothesline has a mass of 0.2 kilograms, and is pulled tight under 100 N of tension. Vivian is hanging up her swimsuit 0 meters from one end when she sees Inchy 2.54 cm (one inch) from the opposite end. She plucks the clothesline sending a terrifying 3 centimeter high wave pulse toward Inchy. If Inchy crawls at 1 inch per second, will he get to the end...

Please answer both
A motocross hike drives off of a jump angled at 45 degree. When the bike leaves the jump, it has a speed of 20 m/n (about 40 mph). To ensure a smooth landing, the landing ramp nerds to be at the same angle as the hikes trajectory when it lands. If the landing ramp is 15 meters lower than the jump, what angle below the horizon should the Undoing ramp slope down? -30 degree -12 degree -58...

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...

A 100 kg nonuniform boom, 6.0 m long, is loosely pinned at the pivot at P. A 700 kg block is suspended from the end of the boom at A. The boom forms a 30 degree angle with the horizontal, and is supported by a cable, 4.0 m long, between points D and B. Point B is 4.0 m from P, and point D is 4.0 m above P. The center of mass of the boom is at point C,...
