Answer:
The mass of the cart is 26.7 kg.
Explanation:
To find this answer use the formula for acceleration first to find how fast the object had to be acccelerating to gain a velocity of 45m/s in 8 seconds flat.
Here's the formula for acceleration:
a = V- V₀ ÷ T (Wher V = final velocity; V₀ = Initial velocity, and T = time)
Plug all known values into the equation and you get -
a = (45m/s - 0m/s) ÷ 8 , which works out to 5.625 m/s²
Once you have this value then you place it into the equation for finding an object's mass, and that formula is:
M = or M =
This works out to 26.6667 kg or approx. 26.7 kg if you are asked to round it to three significant figures.

This can be analyzed through molecular and DNA analysis.When fossils are examined, it should be thorough. Thus, certain anatomical indicators and DNA sequences are observed to describe the overall organism before it died. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
