5. a particle starts from the origin at t=0 with an initial velocity having an xcomponent
of 20 m/s and a ycomponent of 15 m/s. the particle moves in the ryplane with an
component of acceleration only, given by a.- 4.0 m/s2. (a) determine the components
of the velocity vector at any time and the total velocity vector at any time. (b) calculate
the velocity and speed of the particle at 150 s. determine the rand coordinates of the
particle at any time fand the position vector at this time

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

answera compound;

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
