You are driving through town at 14 m/s when suddenly a car backs out of a driveway in front of you. You apply the brakes and begin decelerating at 3.3 m/s2.
PART B)How much time does it take to stop?After braking half the time found in part A, is your speed 7.0 m/s, greater than 7.0 m/s, or less than 7.0 m/s
PART C)Find your speed after braking half the time found in part A.
PLS HELP ME WITH PART C I DID A AND B THANKS!
To solve Part C, we need to determine the speed after braking for half the time found in Part A. First, let's review the information we have:
Initial speed (v0) = 14 m/s
Deceleration (a) = -3.3 m/s^2 (negative sign indicates deceleration)
Time to stop (t) = Found in Part A
To find the speed after braking for half the time, we can use the formula for calculating the final speed (v):
v = v0 + at
Since we want to find the speed after braking for half the time, we multiply the time (t) by 0.5 before plugging it into the formula. Let's substitute the values into the formula:
v = 14 m/s + (-3.3 m/s^2) * (0.5 * t)
To find the time for Part A, you can refer to the calculations you made earlier. Once you have the value, substitute it into the equation and solve for v. The resulting value will be the speed after braking for half the time found in Part A.
