Most aircraft need an airspeed of about 120 knots (61.7 m/s) to lift off. If a fully laden b-52 starts from rest with an acceleration of 4.16 m/s2, how long a runway does it need to be able to take off?
In a local diner, a customer slides an empty coffee cup down the counter for a refill. The cup slides off the counter and strikes the floor at distance d from the base of the counter. (a) If the height of the counter is h, find an expression for the time t it takes the cup to fall to the floor in terms of the variables h and g. t = (b) With what speed does the mug leave the counter? Answer in terms of the variables d, g, and h. v1 = (c) In the same terms, what is the speed of the cup immediately before it hits the floor? v2 = (d) In terms of h and d, what is the direction of the cup's velocity immediately before it hits the floor? ? = radians

Astronomers have discoveredseveral volcanoes on Io, a moon of Jupiter. One of them, namedLoki, ejects lava to a maximum height of 2.00 * 105 m. (a) Whatis the initial speed of the lava? (The acceleration of gravity on Io is1.80 m>s2.) (b) If this volcano were on Earth, would the maximumheight of the ejected lava be greater than, less than, or the same ason Io? Explain.
A bicycle travels 6.70 km due east in 0.240 h, then 14.40 km at 15.0° east of north in 0.310 h, and finally another 6.70 km due east in 0.240 h to reach its destination. The time lost in turning is negligible. Assume that east is in the +x-direction and north is in the +y-direction. What is the magnitude of the average velocity for the entire trip? What is the direction of the average velocity for the entire trip? Enter the answer as an angle in degrees north of east.
