This Question: 1 pt Skid mark analysis is one way to estimate the speed a car was traveling prior to an accident. The speed, that the vehicle was traveling in mies per hour can be approximated by the formula 330df, where d represents the length of the skid marks in feet and represents the drag factor of the road. A vehicle that was involved in an accident on an asphalt road was traveling ata speed of 75 mph when it...
4. (30) An elevated expressway goes through an urban area and crosses a local street. The partial cloverleaf exit ramp is on a 3% downgrade, and all vehicles leaving the expressway must stop at the intersection with the local street. For the following conditions: Maximum speed on expressways 65 mi/ h; Distance between exit sign and exit ramp 300 ft; Letter height of road sign 3 ft; Perception- reaction time 2.5 sec; Maximum superelevation = 0.08; Expressway grade2%. Assume that...
A projectleis fired from a c220 feet above the water at an inclination of 45 to the horizontal with a muzzle velocity of 45 feet per second. The heighth of the projectile above the water is given by h) +x220 where x is the horizontal distance of the projectile from the face of the cift Use this information to answer the following (b) Find the maximum height of the projecte (Write a simplified fraction or an integer as your answer)...
The length of time (T) in seconds it takes the pendulum of a clock to swing through one complete cycle is givenby the formula T=2pi square root of L divided by 32 where L is the length in feet, of the pendulum, and pi is approximately 22 divided by 7. How long must the pendulum be if one complete cycle takes 2 seconds?
1. You are given a formula Lt where L is the length of the object, t is the elapsed time, and v is the object's velocity. You don't know what k represents. What are the SI units of k? 2. The surface area of a certain object is 2 square feet. What is the object's surface area in SI units? The only conversion factor you are allowed to use is 1 inch 2.54 cm
Question 3 (Numerical integration, efficient schemes) The length L of the main supporting cable of a suspension bridge can be calculated by: 4h2 1/2 ral (1 +- L = -x²) dx Joq44 Where a is half the length of the bridge And h is the distance from the deck to the top of the tower where the cable is attached. Determine the length of a bridge with a=80 m and h=18m. Determine the cable length (with associated error of estimate)...
A progressive wave of height η1 = 0.05 m and wave
length λ1 = 0.1 m is generated at r1 = 0.5 m
away the center of a pond with a constant water depth of h = 2 m.
As the waves propagate away from the origin (where they are
generated), they become gravity–capillary waves. The dispersion
relation of gravity-capillary waves in deep water is given as
follows:
where σ ′ = 0.073 N/m is the surface tension for air–water...
Pivot point Consider the figure Center of mass where L is the length of the e<15 Meter stick I meter stick and h is the distance between the pivot point and center of mass of the system. According to the formula T 27T whrI is the moment of mgh inertia about the pivot point. If the parallel axis theorem is used, which of the following equations will best describe an estimate of the moment of inertia of the system? 급...

A formula for estimating the weight of a trout (from measurements) is W = LG2 800 where L is its length and G is its girth (the distance around the body of the fish at its largest point), both measured in inches. The weight of the fish W is in pounds. A trout caught by Ashley is 20% longer and has a girth that is 15% shorter than the one caught by Jane. By how much does the weight of...
