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?

Atruck driver is attempting to deliver some furniture. first, he travels 8 km east, and then he turns around and travels 3 km west. finally, he turns again and travels 13 km to his destination. what is the drivers distance

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
