Answer:
12.35m
Explanation:
Hello! To solve this problem we must consider the following:
1. The car moves with constant speed, which means that the distance traveled is equal to the multiplication of time by speed.
X = VT
we solve the equation for time

2. The bolt moves with constant acceleration, with acceleration of 9.81m / s ^ 2, so we could apply the following equation.
note=remember that "a uniformly accelerated motion", means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.

where
Vo = Initial speed
=0
T = time
=1.588s
g =gravity=9.8m/s^2
Y = bridge height
solving

Answer:
Excuse me what? Or is that the question
Because it’s warmer and more humid
Answer:
100km/hr
Explanation:
From the problem statement we know that distance of the trip is 115km
Expected time for the trip = 1.2hrs
→ If she spends the first half-hour going 90km/hr,
Here time = 0.5hr
speed = 90km/hr
The distance covered;
Distance covered = Speed x time
Distance covered = 90 x 0.5 = 45km
→The remaining distance will be:
Total distance - distance covered
115km - 45km = 70km
→ The remaining time;
1.2hr - 0.5hr = 0.7hr
Speed =
Insert the parameters and solve;
Speed =
= 100km/hr
For the remaining lap, the tourist must travel at a rate of 100km/hr to catch up.
