In SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably mole comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical Intuition. More precisely, show that (a) 1.0m/s=3.6km/h and 1.0m/s=2.2mi/h .
Suppose a cannon is placed at the origin and elevated at an angle of 60 degrees. If the cannonball is fired with a muzzle velocity of 0.18 miles per second, it will follow the graph of the following function, where distances are measured in miles. √3x- 1000x^2 / 2673 How far downrange does the cannonball travel? (Round your answer to two decimal places.)
An athlete performing a long jump leaves the ground at a 31.8 ∘∘ angle and lands 7.65 mm away. What was the takeoff speed? Express your answer using three significant figures and include the appropriate units. If this speed were increased by just 4.0%, how much longer would the jump be? Express your answer using two significant figures and include the appropriate units.
using analytical techniques andchange the second leg of the walk to 25.0 m straight south.(This is equivalent to subtracting B from A —that is, findingR′ = A – B ) (b) Repeat again, but now you first walk25.0 m north and then 18.0 m east. (This is equivalent tosubtract A from B —that is, to find A = B + C . Is thatconsistent with your result?)
Please help me solve this, You drive a car 1500ft to the East, then 2500 ft to the North. If the trip took 3.0 minutes,what was the direction and magnitude of your average velocity, in m/s?(1 m =3.281 ft.)
PLEASE WRITE THE ANSWER IN 10 MINUTES ! ! ! A projectile is launched from the ground as shown in the figure below with an initial speed of V0=47m/s with TETA=42DEGREE and lands on the landing point shown. If X=43m, determine the height of the landing point. Take g=9.81m/s2 and express our answer in units of meters using one decimal place.
A firework rocket is shot upward at a rate of 640ft/sec. Use the projectile formula h=−16t2+v0t to determine the times when the height of the firework will be 1,200 feet. Round your answer to the nearest whole number. ___ seconds and ___ seconds
The battleship US Tennessee is 110 miles due south of the destroyer USS Alaska and is sailing north at 40 mph. If the USS Alaska is sailing east at 25 mph, how long will it be before the distance between the ships is at a minimum? Express your answer in hours and minutes, rounded to the nearest minute.
An athlete performing a long jump leaves the ground at a 27.8 ∘∘ angle and lands 7.63 mm away. What was the takeoff speed? answer using three significant figures and include the appropriate units. If this speed were increased by just 5.0%, how much longer would the jump be? answer using two significant figures and include the appropriate units.
A surveyor measures the distance across a straight river by the following method. Starting directly across from a tree on the opposite bank, she walks d = 78 m along the riverbank to establish a baseline. Then she sights across to the tree. The angle from her baseline to the tree is θ = 36.0°. How wide is the river?_____________________________ m
On a test flight, during the landing of the space shuttle, the ship was 386 ft above the end of the landing strip. If it came in at a constant angle of 5.8°with the landing strip, how far from the end of the landing strip did it first touch ground? The shuttle touched ground _____ ft away from the end of the landing strip. (Round to the nearest ten feet as needed.)
From the roof of the Science Building, 21.0m above the ground, you throw a water balloon at 19.92 m/s exactly horizontally at St. Josephs Auditorium building, which is exactly 36.0 meters south of the Science Building. How far up the wall of St. Joseph's, from ground level, did the water balloon hit? (Report your answer in meters, but only enter the numerical value.)
