Un perro de rescate parte del campamento en búsqueda de una persona extraviada. Se desplaza 3 km al Este, 2.5 km al Norte, 3.5 km al Suroeste y 2 km al Sur, siguiendo la ruta del caminante. ¿A qué distancia y en cuál dirección a partir del campamento se encontraba la persona perdida?

Aparticle initially located at the origin has an acceleration of = 2.00ĵ m/s2 and an initial velocity of i = 8.00î m/s. find (a) the vector position of the particle at any time t (where t is measured in seconds), (b) the velocity of the particle at any time t, (c) the position of the particle at t = 7.00 s, and (d) the speed of the particle at t = 7.00

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2 . how much is the spring compressed x from its natural length?

There are 3 ways heat can be transferred: through solids, called , through liquids and gases , called , and through electromagnetic waves, called
