Hi I am in phyiscs I and it has the problem a runner ran the marathon (approx. 26.1) in 2 hours and 57 min. What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please detalied steps of how to solve this so I can understand it. Thank you!
The kinematic equations can describe phenomena other than motion through space andt ime. Suppose represents a person’s bank account balance. The units of x would be dollars ($) , and velocity ? would give the rate at which the balance changes (in units of, for example, $/month). Acceleration would give the rate at which ? changes. Suppose a person begins with ten thousand dollars in the bank. Initial money management leads to no net change in the account balance so that ? = 0 . Unfortunately, management worsens over time so that ? = −250$/????h . Assuming ? is constant, find the amount of time in months until the bank account is empty.
An arrow is shot straight upwards at 150 m/s, How hight, max height, does the arrow reach? How long did it take for the arrow to reach its max height? What is the total time of flight of the arrow? How fast is it traveling when it reaches its starting level? Make a sketch to visually represnt data given. Make a list of all given values, units, and the variables they represent. Write the general form of the equation you are going to use. Insert the know values and solve the equation.

I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please break it down so I can understand. I tried to solve it how you guys did it but I keep getting another answer. Thank you!

This cannot be hand-written, please type out the solution Use the average time to drop and calculate the distance dropped using the equation given. Then compare this distance to the measured distance. Use Y = 1/2 g t^2, Thus Y= 4.9 t^2 See my attempt attached with the data - teacher indicated my work needed correction, please help Thank you!
Please answer this question within 5 minutes, i will rate you for sure. Two cars start moving from the same point. One travels south at 32 mi/h and the other travels west at 24 mi/h. At what rate is the distance between the cars increasing three hours later?
Dylan has an initial velocity of his slow walk at 5 ft/min^2, and he accelerated to running at 5 fraction numerator f t over denominator m i n squared end fraction for 4 seconds. How much distance did Dylan cover?
A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 26 ft/s. Its height in feet after t seconds is given by y=26t−13t^2A. Find the average velocity for the time period beginning when t=1 and lasting .01 s: .005 s: .002 s: .001 s: NOTE: For the above answers, you may have to enter 6 or 7 significant digits if you are using a calculator.Estimate the instanteneous velocity when t=1.
The following problem involves directions in the form of bearing, which we defined in this section. Remember thatbearing is always measured from a north-south line.A boat leaves the harbor entrance and travels 22 miles in the direction N 42◦E. The captain then turns the boat90◦and travels another 19 miles in the direction S 48◦E. At that time, how far is the boat from the harborentrance, and what is the bearing of the boat from the harbor entrance (see the figure below)? (Round youranswers to the nearest whole number.)
PLEASE ANSWER ONLY LETTER EThe position of a particle is given by the equation s(t) = t3 − 6t2 + 9t, where t is in seconds and s in meters.a) What is the velocity after 2 s? After 4 s?b) Find the instant when the particle reverses directionc) Determine the time intervals when it is moving to the LEFT? RIGHT?d) Find the initial position and the positions when it changes directione) Draw a diagram to represent the motion of a particle.
A rock is dropped from a bridge to the water below. It takes 5.25 deconds for the rock to hit the water. What is the velocity of the rock as it hits the water in metres per second? How far from the water is the bridge (in units of metres to 3 decimal places)? State at the start of the problem which direction is positive (using the up arrow or down arrow) Make a list of all given values, units, and variables they represent. Write the general form of the equation you are going to use. Insert the known variables and solve.
