Find the work w1 done on the bltwo tugboats pull a disabled supertanker. each tug exerts a constant force of 2.10×106 n , one at an angle 10.0 ∘ west of north, and the other at an angle 10.0 ∘ east of north, as they pull the tanker a distance 0.890 km toward the north. ock by the force of magnitude f1 = 80.0 n as the block moves from xi = -5.00 cm to xf = 6.00 cm .

Adelivery truck leaves a warehouse and travels 2.60 km north. the truck makes a left turn and travels 1.25 km west before making another right turn to travel 1.40 km north to arrive at its destination. what is the magnitude and direction of the truck's displacement from the warehouse?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
