A helicopter is ascending vertically with a speed of 5.30 m/s. At a height of 107 m above the Earth, a package is dropped from the helicopter. How much time does it take for the package to reach the ground? [Hint: What is v0 for the package?] Express your answer to three significant figures and include the appropriate units. My Answer is that t= 4.163 but what unit is it? I tried s, m/s, min but none of them were correct. PLEASE HELP CONFIRM MY ANSWER and THE UNIT along with 4.163
A pilot flies in a straight path for 1 hour 45 minutes. She then makes a course correction, heading 30 degrees to the right of her original course, and flies 2 hours 30 minutes in the new direction. If she maintains a constant speed of 340 mi/h, how far is she from her starting position? Give your answer to the nearest mile.
A person drops a rock from the edge of a cliff that is 1350 ft high. The initial acceleration is a=−32 ft/sec^2. 1. What is the velocity equation? Use t as the variable and v for the velocity. 2. What is the displacement equation? Use t as the variable and s as the displacement. 3.What time did it hit the ground? (Hint: s=0) 4. What was the velocity just before impact?
The expression for velocity is given: v=d/t - v0. The variables are given: d= 35.0 meters, t= 9.00 seconds, and v0= 3.00meters/seconds. What is the velocity?
How high (in ft.) will a ball rise if is tossed vertically upward with a speed of 100 ft/s? Hint: 1 inch = 2.54 cm.
The height of a projectile fired straight up in the air with an initial velocity of 64 ft/s is h = 64t - 16t2, where h is height in feet and t is time in seconds. The table represents the data for another projectile. Which projectile goes higher? How much higher? Table Data Time (t) Height (h) 0.5 20 1 32 1.5 36 2 32
The height h, in feet, of a ball above the ground t seconds after being thrown upward with a velocity of 64 ft/s is given by h = −16t2 + 64t + 9. After how many seconds will the ball be 57 ft above the ground? (Enter your answers as a comma-separated list.)
A person standing at the edge of a cliff throws a rock upward from a height of 350ft above ground level with an initial velocity of 65⁢ft/s. What is the velocity of impact when the rock reaches the bottom of the cliff? Round any intermediate calculations, if needed, to no less than six decimal places, and round your final answer to two decimal places. (Hint: Use h(t)=−16t2+65t+350 as the position function, where hh is in feet, tt in seconds. Ignore air resistance.)
In an 8.00 kmkm race, one runner runs at a steady 11.2 km/hkm/h and another runs at 14.9 km/hkm/h. How far from the finish line is the slower runner when the faster runner finishes the race? Express your answer in kilometers to three significant figures.
