a solid ball rolls smoothly from rest (starting at height H = 6.0 m) until it leaves the horizontal section at the end of the track, at height h = 2.0 m. How far horizontally from point A does the ball hit the floor?

What is the radial acceleration of the blade tip expressed as a multiple of the acceleration due to gravity, g? Express your answer as a multiple of g.

Problem 2: A tal, cylindrical chimney is toppling over as its base has ruptured. Let us say that the height H of the chimney is significantly larger than its thickness, so we may treat the chimney as a thin, rigid rod of length H. At the instant when the chimney is at angle 0o with respect to the vertical, what is the: (a) angular speed w of the top of the chimney? (b) radial component a, of the acceleration of the top? (c) tangential component aț of the acceleration of the top? (d) the specific value of 60 at which aț is equal to g?

In the figure here, a small, solid, uniform ball is to be shot from point P so that it rolls smoothly along a horizontal path, up along a ramp, and onto a plateau. Then it leaves the plateau horizontally to land on a game board, at a horizontal distanced from the right edge of the plateau. The vertical heights are h, = 3.5 cm and h2 = 1.70 cm. With what speed must the ball be shot at point P for it to land at d = 4.5 cm? Ball

A helicopter propeller blade starts from rest and experiences a constant angular acceleration of 25.0 rad/s2. Find the speed of a point on the blade 2.70 m from the axis of rotation when the blade has completed 20 revolutions

In the figure, a solid 0.1 kg ball rolls smoothly from rest (starting at height H = 6.3 m) until it leaves the horizontal section at the end of the track, at height h = 2.0 m. How far horizontally from point A does the ball hit the floor? Number Units

Point A of the circular disk is at the angular position 0 = 0 at time t = 0. The disk has angular velocity wo = 0.29 rad/s at t = 0 and subsequently experiences an angular acceleration a = 1.8t where t is in seconds, and a is in radians per second squared. Determine the velocity and acceleration of point A in terms of fixed i and j unit vectors at time t = 2.7 s. Assumer = 145 mm. α Answers: VA = aд = 90 (i ( i 0 6.806 i + i + i i 1 0.705 j) m/s j) m/s²
