- Consider a projectile launched at a height h feet above the ground and at an angle ? with the horizontal. If the initial velocity is v0 feet per second, the path of the projectile is modeled by the parametric equations x = t(v0 cos(?)) and y = h + (v0 sin ?)t - 16t2.Let h=6, v0=63.25, and ?=0.79. Find the maximum height of the projectile. (Round your answers to two decimal places.)arrow_forwardThe continuity equation is also known as (a) Conservation of mass (b) Conservation of energy (c) Conservation of momentum (d ) Newton’s second law (e) Cauchy’s equationarrow_forward1. Any equation that comes out of the differential approach is valid at every point in the flow field. On the other hand, the integral approach gives us a point by point value and not an average value. True or False 2. During the analysis of fluid flow, we are more often interested in obtaining the average velocity, and one of the common ways of obtaining the average velocity is to take an average across the flow cross-section. This is called area-average velocity, average along the direction parallel to the principal direction of flow. True or False 3. A crude oil with a density of 875 kilogram per cubic meter is pumped and flowing at 1.5 meter per second through a pipeline 1 meter in diameter. The maximum viscosity of the oil to exhibit a laminar flow behavior is 625 centipoise. True or Falsearrow_forward
- A wooden ballistic pendulum, with a mass equal to 10 kg, suspended by a wire 1 meter long, is hit at t=0 s by a 10 gram bullet, traveling at a speed of 300 m/s, which becomes stuck in it (Use g=9.8m/s2). With respect to the question, consider the following statements. I) The expression that allows to calculate the angle \theta (in rad) between the wire and the vertical as a function of time is \theta(t)=0.096 \sin(3.13\; t). II) The first instant of time in which the pendulum reaches its maximum height is t=1s. III) The maximum angular acceleration is approximately 0.94 rad/s2.

Round off your final answer to two decimal places.arrow_forwardPlease help me in answering the following practice question. Thank you for your help. A Newtonian fluid is flowing in an infinitely long round pipe of diameter M or radius N = M/2 and inclined at angle α with the horizontal line. Consider the flow is steady (dρ/dt=0), in-compressible, and laminar. There is no applied pressure gradient (dP/dz= 0) applied along the pipe length (z-direction). The fluid flows down the pipe due to gravity alone (gravity acts vertically downward). Adopt the coordinate system with z axis along the centre line of the pipe along the pipe length.Derive an expression for the z-component of velocity u as a function of radius N and the other parameters of the problem. The density and viscosity of the fluid are ρ and u, respectively.Please list all necessary assumptions.arrow_forward
