A child of mass 26 kg , is sliding down a water-slide that has an angle of 32 deg. If the water lubricates the slide to a frictionless surface, and the slide is 9 meters long.  What is the child's velocity at the bottom?

An old car tire (I=MR2)isplaced at a vertical height of 2.5 m on a slopethat makes a 18°angle with the horizontal.It is released from rest and rolls without slipping to the bottom of the slope. What is the tire’s velocity at the bottom? Also calculate acceleration.

A 10 m/s В A 1000-kg Jeep travels along a straight 500-m portion of highway (from A to B) at a constant speed of 10 m/s. At B, the Jeep encounters an unbanked curve of radius 50 m. The Jeep follows the road from B to C traveling at a constant speed of 10 m/s while the direction of the Jeep changes from east to south. ... 50 m N C W E S What is the magnitude of the acceleration of the Jeep as it travels from B to C? A 10 m/s? в) 5 m/s? C 20 m/s2 D 2 m/s2

A clown is juggling four balls simultaneously. Students use a video tape to determine that it takes the clown 0.9 s to cycle each ball through his hands (including catching, transferring, and throwing) and to be ready to catch the next ball. What is the minimum vertical speed the clown must throw each ball upward with?

A soccer player kicks a ball, while imparting spin to bend it. The ball starts on the ground and is kicked with an initial velocity of 15 ?/?, at an angle of elevation 30 degrees. Assume the ball was kicked north and the spin creates a constant acceleration ? to the west, which is what makes the ball follow a curved path. If the ball lands 8 meters west of the starting point, what is the value of ?? Assume the standard value of ? = 9.8 ?/?2.

A 70 kg person on a merry go round is spinning with speed 5 m/s. If they experience a centripetal force of 583N, how far from the center of the merry go round are they sitting? Express in meters.

A 70g person on a merry go round is spinning with speed 5m/s. If they experience a centripetal force of 583N, how far from the center of the merry go round are they sitting?

A pendulum is 0.890 m long, and the bob has a mass of 1.00 kg. At the bottom of its swing, the bob’s speed is 1.60 m/s. a. What is the tension in the string at the bottom of the swing? answer in N b. The tension is greater than the weight of the bob because of which of the following? its horizontal component is increasing from zero. the bob has zero acceleration. the bob has a downward acceleration, so the net Fy must be downward. the bob has an upward acceleration, so the net Fy must be upward.
