Question 4 of 10 < >-/1 E :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 distance d from the right edge of theplateau. The vertical heights are h₁ = 3.5 cm and h₂ = 1.90 cm. With what speed must the ball be shot at point P for it to land at d = 3.0cm?VOPBall=6%eTextbook and MediaHintSave for Laterm/s-dAPR8tvMacBook ProAttempts: unlimitedSubmit Answer

You are a visitor aboard the New International Space Station, which is in a circular orbit around the Earth with an orbital speed of ?o=2.45 km/s�o=2.45 km/s . The station is equipped with a high velocity projectile launcher, which can be used to launch small projectiles in various directions at high speeds. Most of the time, the projectiles either enter new orbits around the Earth or eventually fall down and hit the Earth. However, as you know from your physics courses at the Academy, projectiles launched with a sufficiently great initial speed can travel away from the Earth indefinitely, always slowing down but never falling back to Earth. With what minimum total speed, relative to the Earth, would projectiles need to be launched from the station in order to "escape" in this way? For reference, recall that the radius of the Earth is ?E=6370000 m�E=6370000 m, the mass of the Earth is ?E=5.98×1024 kg�E=5.98×1024 kg , the acceleration due to gravity on the surface of the Earth is ?=9.81…
An object rotates about a fixed axis, and the angular position of a reference line on the object is given by θ = 0.350e3t, where θ is in radians and t is in seconds. Consider a point on the object that is 6.00 cm from the axis of rotation. At t = 0, what are the magnitudes of the point's (a) tangential component of acceleration and (b) radial component of acceleration?
A solid ball of radius r begins to roll down a hemisphere with radius R. Find the angular speed of the ball at the moment it leaves the surface of the hemisphere. Obviously, r < R.
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.

A bicycle is turned upside down while its owner repairs a flat tire. A friend spins the other wheel and observes that drops of water fly off tangentially. She measures the heights reached by drops mov- ing vertically (Fig. P7.8). A drop that breaks loose from the tire on one turn rises vertically 54.0 cm above the tangent point. A drop that breaks loose on the next turn Figure P7.8 rises 51.0 cm above the tangent point. The radius of the wheel is 0.381 m. (a) Why does the first drop rise higher than the second drop? (b) Neglecting air friction and using only the observed heights and the radius of the wheel, find the wheel's angular acceleration (assuming it to be constant). Problems 8 and 69.
A box descends a ramp and lands on a surface. The box exits the side of the table as it meets the bottom of the tamp, becoming a horizontal projectile. It lands x metres away from the table.

A 0.50-kg ball that is tied to the end of a 1.7-m light cord is revolved in a horizontal plane, with the cord making a θ = 30° angle with the vertical. An illustration shows a ball suspended from a string. The string forms an angle θ with the vertical as its top end is held stationary in space while the ball moves along a horizontal circular path below. The center of the circular path is shown to be directly below the top end of the string. (a) Determine the ball's speed. m/s(b) If, instead, the ball is revolved so that its speed is 3.8 m/s, what angle does the cord make with the vertical? °(c) If the cord can withstand a maximum tension of 9.6 N, what is the highest speed at which the ball can move? m/s
