A car is being towed by an SUV using towing straps as shown in the sketch and free-body diagram above. The 5800 N force represents:
the backward force the road exerts on the car.
the upward force the road exerts on the car.
the force exerted by the towing straps on the car
the gravitational force acting on the car.

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?

The air that we breath is made mostly of which gaseous molecule

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.
