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.
(Pp is the purple flower with the unknown genotype, pp is the white flower)
First scenario:
Pp x pp
first generation: Pp Pp pp pp (two purple, two white flowers)
Second scenario:
PP x pp
second generation : Pp Pp Pp Pp (four purple flowers)
