A powerful motorcycle can produce an acceleraDon of 3.50 m/s2 while traveling at 90.0 km/h. At that speed, the forces resisDng moDon, including fricDon and air resistance, total 400 N. (Air resistance is analogous to air fricDon. It always opposes the moDon of an object.)
What is the magnitude of the force that motorcycle exerts backward on the ground to produce its acceleraDon if the mass of the motorcycle with rider is 245 kg?

Auniform crate c with mass mc is being transported to the left by a forklift with a constant speed v1. what is the magnitude of the angular momentum of the crate about point a, that is, the point of contact between the front tire of the forklift and the ground

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
