The problem is, I don't think that you estimated for letter a, so you can't do letter b.
To solve this question, we have to find the acceleration of the car first. Acceleration refers to the rate of change of velocity of an object with respect to time.
Acceleration [A] = [V0 - V1] / T
Where VO = Initial velocity and V1 = Final velocity T represent time.
V0 = O
V1 = 18
T = 8
A = [ 0 - 18] / 8 = - 2.25
A = - 2.25 M/S^2.
To find force, we are going to use the formula: F = MA
F = ?
M = 1550
A = - 2.25
F = 1550 * - 2.25 = 3487.5
Therefore, F = -3487.5 N
Answer:
<u>I will take around 1 year and 8 months to earn $ 45 of interest on this investment</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Interest earned = $ 45
Investment = $ 790
Annual simple interest rate = 3.4% = 0.034
2. How much time would it take to earn $45?
Let's recall the formula for calculating the simple interest of an investment:
A = P * (1 + rt)
Replacing with the values we already have:
835 = 790 + (1 + 0.034t).
Where t is the time we want to calculate
835 = 790 + 26.86t
26.86t = 835 - 790
26.86t = 45
t = 1.68 (Rounding to the next hundredth)
<u>t ≅ 1 year and 8 months</u>
