A single constant force
In the vertical jump, an athlete starts from a crouch andjumps upward to reach as high as possible. Even the best athletesspend little more than 1.00 s in the air (their "hang time"). Treatthe athlete as a particle and let be his maximum height above the floor. Toexplain why he seems to hang in the air, calculate the ratio of thetime he is above /2 moving up to the time it takes him to go from thefloor to that height. You may ignore air resistance.
I think I have to use the formula
A lunch tray is being held in one hand, as the drawing illustrates. The mass of the tray itself is 0.200 kg, and its center of gravity is located tits geometrical center. On the tray is a 1.00 kg plate of food and a 0.190 kg cup of coffee. Obtain the force T exerted by the thumb and the force F exerted by the four fingers. Both forces act perpendicular to the tray, which is being held parallel to the ground.
Turning back to high school math can be essential to understand engineering tasks that you may encounter later. The high school math problems have all the basics that have good equations and answers, which will let you see things clearly. The list of high school math questions below will help you identify your weaknesses and find various solutions. Taking a look at high school math equations, you will see certain parts that can be applied to Physics. In either case, the best way is to learn by example, which is why high school math problems with answers will be essential.
