The correct answers are B, D and E
Explanation:
The best way to find if each of the statmenet is true or false is to find the percentage in each case. To do this, follow this general formula: Total number / 100 (100 representes the total) x specific percentage. Now, let's apply this formula in each statement
A)
30 ÷ 100 = 0.3 x 15 = 4.5 (This statement is false)
B)
80 ÷ 100 = 0.8 x 25 = 20 (This statement is true)
C)
50 ÷ 100 = 0.5 x 30 = 15 (This statment is false)
D)
60 ÷ 100 = 0.6 x 30 = 18 (This statement is true)
E)
20 ÷ 100 = 0.2 x 40 = 8 (This statement is true)
First calculate the time it takes to reach the building
using the x-component of the velocity.
t = 57.6 m / (42.7 m/s * cos35.2) = 1.65 s
Then we calculate the height y using the y-component of
the velocity:
y = (42.7 m/s * sin35.2) * 1.65 s – 0.5 (9.81 m/s^2) (1.65
s)^2
<span>y = 11.26 m</span>
