Dos bloques de masa 0,5kg cada uno se mueven hacia la derecha con velocidades de 2 m/s y 1 m/s inmediatamente antes del choque, el que se mueve a 2 m/s va detrás del que se mueve a 1 m/s. Si, después del choque, el que iba a 2m/s reduce su velocidad a la mitad , ¿con qué velocidad se mueve el otro?

Ahollow metal sphere has 6 cm and 11 cm inner and outer radii, respectively. the surface charge density on the inside surface is −100nc/m2. the surface charge density on the exterior surface is:

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

How is the gravitational force related to the distance between two objects?
