- Find the elevation h (km) where the weight of an object is one-tenth its weight on the surface of the earth.The wheels of a car have radius 10 in. and are rotating at 700 rpm. Find the speed of the car in mi/h.A weight of 300.0 kg is pulled from the water by the setup consistıng of two slanted poles and a moveable rope as shown in the figure below Take the value of acceleration due to gravityg=98m's (Round your answer to one decimal place.) 6.6 m 5 m 5 m 3 m 3 m
- Let us say that we have a ladder with its own length (L) and its own mass (m) this ladder just so happens to make a (θ) degree angle with a wall. The center of mass of this ladder is 1/3 of the way up from the bottom (it gets narrower towards the top). A person of mass M then decides to climb the ladder until he comes to the halfway point. Wall has no friction but the ground has on the ladder.. a) Draw this situation and label forces so you may set up the statics equations. b) Find the force on the ladder due to the ground (both x and y components) and the force on the ladder due to the wall.If the local gravitational acceleration is 32.0 ft/s2, find the weight W of an object with mass of m = 1000 lbm.Given: Va and 0 Find: Horizontal distance it XB travels and vc- B VA = 10 m/s Plan: Apply the kinematic relations in x- and y- 30° directions.

Determine the minimum speed (in m/s) of the box required at point T such that it can stay on the loop.Q4) A grasshopper leaps into the air from the edge of a vertical eliff, as shown in Figure.

- Modern roller coasters have vertical loops like the one shown in the figure. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats. Part (a) What is the speed of the roller coaster, in meters per second, at the top of the loop if the radius of curvature there is 15 m and the downward acceleration of the car is 1.3g? Note that g here is the acceleration due to gravity. Part (b) The beginning of this roller coaster is at the top of a high hill. If it started from rest at the top of this hill, how high, in meters, above the top of the loop is this initial starting point? You may assume there is no friction anywhere on the track. Part (c) If it actually starts 3.5 m higher than your answer to the previous part (yet still reaches the top of the loop with the same velocity), how much energy, in joules, did it lose…3. An engineer is designing the runway for an airport. Of the planes that will use theairport, the lowest acceleration rate is likely to be 3 m/s2. The takeoff speed forthis plane will be 65 m/s. Assuming this minimum acceleration, what is the minimum allowed length for the runway?Find the acceleration of an open cylinder with 5 m diameter and holding - 6 m of water if the force acting on the sides is 90 kN.
