1. A 15.0 kg child and a 25 kg child sits at opposite ends of a 4 m see saw pivoted at its center. Where should a third child whose mass is 20 kg sit in order to balance the see saw?

Consider three charges, one of magnitude +2Q and other two have magnitude -Q. They are
placed in a constellation as depicted in the figure below. Find out the electric intensity at some
spherical point P(r, theta,

consider the binomial distribution pn (n) for n = 16 and p = q = 1/2. what is the value of pn (n) for n = σn/2? what is the value of the product pn (n = n)σn?

Assume the frictional force on the boat is equal to 1804 N, and the boat is accelerating at a rate of 1.20 m/s2. What force does the truck need to pull on the boat- counteracting the friction- to accelerate it if the trailer (boat) has a mass of 300 kg

A unicycle wheel with a diameter of 0.400 [m] starts rotating from rest with constant angular acceleration 2.00 [rad/s^2]. What is the tangential speed of the wheel’s rim after two revolutions?

The Barangay council of San Jose will conduct a fireworks display on the evening of December 24. As part of the organizing team, you have to make sure that the firework residue (assuming it will make a parabolic path) will not land on the viewer's area which is 25 m away. If each of the fireworks will be launched at a constant initial velocity of 30m/s. at what angle must you suggest the Head Organizer to fill the fireworks to avoid it from landing on the people watching?

Jane and Wussle are playing siatong on the field. They both agreed that the player with the farthest siatong to land will treat the loser with a snack. Jane hit her stick with an initial velocity of 12 m/s at 30° angle while Wussle launched his siatong with 15m/s at 25°

a. How far did wussle's siatong landed?
