A 31.0 kg child on a swing is displaced by a maximum angle of 20 degrees to the vertical above her rest position. Assuming no loss of energy and that the swing's rope is 2m long: a) At what point during the swing will she attain her maximum speed? b) What will be her maximum speed through the subsequent swing? c)Assuming this maximum height was the result of one push from her parent, what was the average force exerted by...

A child is sitting on the seat of a swing with ropes 10 m long. Their father pulls the swing back until the ropes make a 37o angle with the vertical and then releases the swing. If air resistance is neglected, what is the speed of the child at the bottom of the arc of the swing when the ropes are vertical?

A child with a weight of 200 N swings on a playground swing attached to 2.00-m-long chains. What is the gravitational potential energy of the child- Earth system relative to the child's lowest position at the following times? (a) when the chains are horizontal j (b) when the chains make an angle of 30.0° with respect to the vertical J (c) when the child is at his lowest position A pendulum bob with a mass of 0.370 kg is attached...

on 41. A 25 kg child plays on a swing having support ropes that are 2.2 m long. A friend pull back until the ropes are 42 degrees from the vertical and releases her from rest. (a) What is the potential energy of the child just as she is released, compared with the potential energy at the bottom of the swing? (b) how fast will she be moving at the bottom of the swing? (c) how much work does the...

Consider the conical pendulum which has a mass of 8kg and a rope 5 meters long, when rotating the rope forms an angle of 10 degrees with the vertical (see figure). Determine a) the vertical and horizontal components of the force exerted by the rope on the mass, b) the radial acceleration, c) the tangential speed, d) the period of rotation (Draw the vector system) We were unable to transcribe this image

(1 point) Consider a cannonball launched along the path p(t) (400t + 70, 300t – 350, 37t – 16t?), with length units in feet and time units in seconds. When does it return to the height from which it was launched? (The coordinate system is right-handed, with z the vertical axis.) Answer: t= What is its velocity then? Answer: kg ft kg m s but here we can measure it in Momentum is mass times speed, usually measured in impact...

A batter hits a baseball 3 feet above the ground toward the center field fence, which is 10 1. feet high and 400 feet from home plate (where the batter stands when he hits the ball). The bal leaves the bat with a speed of 115 ft/s at an angle of 50° above the horizontal. Is it a home run? That is, does the ball clear the fence? You do not need to derive the formulas for projectile motion from...

The Green Monster, as shown below, is a wall 37 feet high in left field at Fenway Park in Boston. The wall is 310 feet from home plate down the third base line. If the batter hits the ball 4 feet above the ground, neglecting air resistance, determine the minimum speed that the bat must impart to the ball that is hit over the Green Monster. COVIDIE CVS.
