A 0.69 kg mass is observed to accelerate at 8.16 m/s2 in a direction 30.5° north of east. There is a force directed north acting on the object and a force directed east acting on the object. What is the magnitude of the force acting east on the object?

  • physics -

    forceNorth= mass*accelerationNorth
    forceEast= mass*acceleartionEast

    so break up the acceleration in to N, and E components.

  • physics -

    what are the conditions neccessary for a body to perform simple harmonic oscillation
