## Assume the spring to be unstretched at θ = 0. Figure P1. 69 Solution:69In the figure let the mass at θ = 0 be the lowest point for potential energy. Then, the height of the mass m is (1-cosθ) 2 . Kinematic relation: x = 1. 7575Consider Problem 1.74 with k = 500,000 N/m, m = 2000 kg, J = 200 m 2 ⋅kg/rad, r = 30 cm, and c = 8000 kg/s. But kg/(m.s^2) tells us that mass, length, and time squared will affect the pressure on something. = 0 − 2 g(0 − h ) v = 2 gh = 2 (9.8 m /s2)(10 m ) =14 m /s Initial: k = 1 2 mv 2 = 0 Final : k = 1 2 mv 2 = 1 2 (3 kg )(14 m /s)2 = 294 J So as the ball falls, its kinetic energy increases. It is the gravitational force that accelerates the ball, causing the speed to increase. The increase in speed also increases the kinetic energy. ### However, because kinetic energy is given by K = 1 2 m v 2 K = 1 2 m v 2, and velocity is a quantity that is different for every point on a rotating body about an axis, it makes sense to find a way to write kinetic energy in terms of the variable ω ω, which is the same for all points on a rigid rotating body. For a single particle rotating (c) If the string has a mass/unit length of m = 0.012 kg/m, determine the tension in the string.

In our example, lifting a weight straight up, the acceleration we're fighting is due to gravity, which equals 9.8 meters/second 2. Calculate the force required to move our weight upward by multiplying (10 kg) x (9.8 m/s 2) = 98 kg m/s 2 = 98 Newtons (N). If the object is being moved horizontally, gravity is irrelevant.
