Answer:
1. 75
2. Cornbits
Step-by-step explanation:
1. 12/100 = 9/x
x = 75
2. Tasty Oats || 100/12 = 8.33g protein/gram cereal
Cornbits || 45/5 = 9g protein/gram cereal
To find the height that the rocket has reached, we can use the following equation to calculate distance.
s = ut + 1/2 at²
s - distance - h
u - initial velocity - 64 ft/s x 0.3048 m/ft = 19.5 m/s
a - acceleration, since the rocket is travelling upwards against gravitational acceleration, its said to be deceleration. therefore value is -9.8 ms⁻²
t - time taken - t seconds
substituting values in the equation
h = 19.5 ms⁻¹ x t s - 1/2 x 9.8 ms⁻² x (t s)²
h = 19.5t - 4.9t²
Im pretty sure you are i have done this question before and im pretty sure thats what i put and i got it right. plus just go with your gut
