A 24.0 kgkg box is held at the top of a 9.40 mm long delivery ramp that makes a 17.0 degreedegree angle with the horizontal. When the box is released, it slides down the ramp, with a constant 48.0 NN frictional force exerted on it over the full 9.40 mm . What kinetic energy does the box have at the bottom of the ramp?

If the radius of curvature of the cornea is 0.75 cm when the eye is focusing on an object 36.0 cm from the cornea vertex and the indexes of refraction are as described before, what is the distance from the cornea vertex to the retina? express your answer to two significant

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
