Calculating Nozzle Flow Rate To work out the flow rate of water from a nozzle we need to work out the volume in a given period of time. To do this we work out the area of the nozzle and …

A potato is launched vertically upward with an initial velocity of 100 ft/s from a potato gun at the top of an 85-foot-tall building. The distance in feet that the potato travels from the ground after …

Sep 19, 2010 · To find the initial velocity of an object launched at a 33-degree angle that lands 85 meters away, the correct formula is range = v0^2 * sin (2θ) / g. The calculated initial velocity is …

Aug 28, 2023 · A ball thrown straight upward moves initially with a decreasing upward velocity. What are the directions of the velocity and acceleration vectors during this part of the motion?

Nov 19, 2014 · The discussion clarifies the distinction between speed and velocity, noting that speed is a scalar quantity representing magnitude, while velocity is a vector that includes …

A tube rotates in the horizontal xy plane with a constant angular velocity ω about the z-axis. A particle of mass m is released from a radial distance R when the tube is in the position shown. …

A particle moving along a straight line travels the distance s = 2 t 2 − 3 t in time t. (i) Find the velocity v and acceleration a at time t. (ii) Sketch graphs of s and v as functions of t in the …

May 14, 2010 · To calculate the height of a bouncing ball under Earth's gravity, the conservation of energy principle is essential. The initial potential energy (mgh) converts to kinetic energy …
