M I f. m M The object as shown slides up the ramp, which is free to roll on a frictionless surface. (Problems 3-5) 3. What is vf for the two objects (in terms of m, theta, g, vo, H)?

m. m. W, W, EF = m,a W, -T = m,a EF = m,a T-W, = m,a From these two equations, we can now eliminate Tand solve for the acceleration, a. Pre-Lab Question # 4: Solve the above problem for the acceleration in terms of the masses and the acceleration due to gravity; i.e. find the function a(m.m2, g). If, m,=4kg and m2=10kg, what is the acceleration? What is the tension in the string?

Name: ID: A 3. A ball is thrown horizontally from the top of a building 0.10 km high. The ball strikes the ground at a 65 m horizontally away from and below the point of release. What is the speed of the ball just before it strikes the ground? point a. 43 m/s 47 m/s b. 39m/s d. 36 m/s C. 14 m/s 4. A baseball is hit at ground level. The ball is observed to reach its maximum height above ground level 3.0 s

ha body that will guid. What Have I Learned So Far? 1. The circular path of the moon, which has a radius of approximately 3.84 x 105 km, as it revolves around Earth makes the moon complete one revolution in 27.32 days. What is the speed of the moon and its radial acceleration? e circular rack. Solution: is 2. Bodies that are on the surface of Earth are undergoing radial acceleration due to Earth's rotation on its axis. Our planet completes one rotation in 24 hrs and has a radius of about 6371 km. a. What is the radial acceleration of a body found at Earth's equator in m/s2. b. If a certain body will be placed at 25° latitude, compute its radial acceleration. in Action ter edge force. Solution: move
