Alright let's start this off with our basic equation!
Accerlation (
a) = ?
Initial velocity (
V1)= 60 mph = 88 ft/s (because we HAVE to convert mph to ft/s to match time)
Final velocity (
V2) = 0 ft/s because the car stops
Time (
t) = 4 seconds
a =
a =
a =
a = -22
Therefore, your acceleration is -22 ft/s² !! Hope this helped and was one of the branliest answers :')
Answer:
Change in momentum = 60kgm/s.
Explanation:
<u>Given the following data;</u>
Mass, m = 12kg
Initial velocity, u = 9m/s
Final velocity, v = 14m/s
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
To find the change in momentum;
Mathematically, change in momentum is given by the formula
Substituting into the equation, we have;
<em>Change in momentum = 60kgm/s.</em>
C = Q/V, and since C is a constant, if voltage is doubled, charged will be doubled as well. Therefore charge will be 2Q
Answer:
Answer:
A. for every object submerged partially or completely in a fluid
Explanation:
This is following Archimedes principle which states that the upward buoyant force that is exerted on a body immersed in a fluid, whether FULLYor PARTIALLY submerged, is equal to the weight of the fluid that the body displaces.
