Jean-Luc likes to run errands on Saturday mornings. He leaves his house at 10:00 a. m. and first heads to the post office to mail a package. Then, he heads to the pet store to buy food for his goldfish. • a. What is the distance of this trip?

• b. What is his displacement when he is at the post office?

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

  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

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
