A wave of amplitude 0.40 m interferes with a second wave of amplitude 0.3 m traveling in the same direction. (a) What is the largest resultant amplitude that can arise, and under what conditions will this maximum occur? m The two waves interfere destructively. The two waves interfere constructively. (b) What is the smallest resultant amplitude that can arise, and under what conditions will this minimum occur? m The two waves interfere destructively. The two waves interfere constructively.
What is the magnetic field strength. Consider a ladder 5 meters tall, and a 150 kg weight on top of it. The ladder is leaning against the wall.
Kieran takes off down a 50m high, 10° slope on his jet-powered skis. The skis have a thrust of 320 N. The combined mass of skis and Kieran is 50 kg (the fuel mass is negligible). Kieran's speed at the bottom is 40 m/s. What is the coefficient of k..
A student wearing frictionless in-line skades on a horizontal surface is pushed by a friend with a constant force of 23.00N. How far should the student be pushed, starting from rest, so that her final kinetic energy is 283J.

Find out the constant force that must be exerted on him to bring him to rest in a distance of 1.2 m in a time interval of 0.20 s.opposite the fullback's direction of motion.
A .450 kg ice puck, moving east with a speed of 3m/s, has a head-n collision with a .900 kg puck initially at rest. Assume a completely elastic collision, what will be the speed and direction of each object after collision.
An arrow is fired horizontally with a speed of 68. m/s directly at the bulls eye of a target 50 m away. When fired, the arrow is 120-m above the ground. How far short of the target does it strike the ground.
A vertical scale on a spring balance reads from 0 to 175. The scale has a length of 12 from the 0 to 175 reading. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.8.
