0m. Neglecting friction between the car and road‚ find (a) v and (b) the horizontal force exerted on the car. 25) A daredevil on a motorcycle leaves the end of a ramp with a speed of 35.0 m/s as in the figure P5.25. If his speed is 33.0 m/s when he reaches the peak of the path‚ what is the maximum height that he reaches? Ignore friction and air resistance. 31) A horizontal spring attached to a wall has a force constant of 850 N/m. A block of mass 1.00 kg is attached to the spring and oscillates

yields two integrations: x = x0+v0t+1/2at2 v = v9+at These two expressions show the relationship between position‚ velocity‚ and acceleration at a given time. Newton’s 2nd law states that the acceleration of an object depends on the net force acting upon the object and the mass of the object. If there were no friction in this experiment‚ then the acceleration of the glider would be equal to acceleration of gravity multiplied by the angle between the air track and the horizontal table (g

Vectors‚ Forces‚ and Equilibrium 1.1 Purpose The purpose of this experiment is to give you a qualitative and quantitative feel for vectors and forces in equilibrium. 1.2 Introduction An object that is not accelerating falls into one of three categories: • The object is static and is subjected to a number of different forces which cancel each other out. • The object is static and is not being subjected to any forces. (This is unlikely since all objects are subject to the force of gravity

there is a constant relationship between these forces. Lift is the upward force created by the effect of airflow as it passes over and under the wing. The airplane is supported in flight by lift. Weight‚ which opposes lift‚ is caused by the downward pull of gravity. Thrust is the forward force which propels the airplane through the air‚ which varies with the amount of engine power being used. Opposing thrust is drag‚ which is a backward‚ or retarding‚ force which limits the speed of the airplane. I’m

biomechanics behind a volleyball overhand serve and why we need force‚ acceleration‚ gravity‚ levers and power to produce the most optimum serve. The biomechanics principles are force and motion‚ momentum‚ leverage and fluid mechanics. (http://codysbiomechanisvolleyballblog.blogspot.com.au/) Force and motion. This principal is found mostly in the sprinting and jumping portions of the serve! When the player sprints‚ they exert a force against the ground in an angle. The momentum from the sprint is

Buoyant Forces The purpose of this lab is to calculate buoyant forces of objects submerged in water. The first step in the lab was to measure the mass of a metal cylinder‚ which was found to be 100g‚ and then to calculated it’s weight‚ which was .98 newtons. Then next step was to measure the apparent weight of the cylinder when it is completely submerged in a bath of water using the formula Wa=ma*g ‚ this was found to be 88.5grams. Knowing these two numbers‚ the buoyant force that the water
