The dimension of position is 'L'
The dimension of velocity is 'L/T'
The dimension of acceleration is 'L/(T^2)'
from this we can show that the equation is dimensionaly consistent

If a is acceleration, v is velocity, x is position, and t is time, then check the validity (wrong or correct) of the following equations using dimensional analysis: a) t2 = 2x/a b) t = x/v c) a = v/x d) v = a/t ALSO , The term 1/2 PV^2 rv2 occurs in Bernoulli’s equation in Chapter 15, with P being the density of a fluid and v its speed. Find the dimensions of 1/2 PV^2 Thank you in advance...
Physics 2010 Spring 2019 One dimensional motion tion due to gravity is a constant 9.81 m/s?. Imagine you throw a ball straight into the air with an initial velocity of 20 m/s. Let's call the point where you release the ballx. (a) Velocity and acceleration are both vectors. What is the direction of both of these vectors? (b) Find an equation for the velocity of the ball as a function of time. Remember to include the direction! Plot the magnitude...
Problem 36 bclow presents a model describing the drag of a fluid medium that is released from rest at time t 0 (same initial conditions). Using Newton's Second Law, you build a model of the form particle moving through a (governing equation (initial velocity) mi mg-F drag '0 (0)(0)a (t) is the particle's position, m is the mass of the particle, g is the acceleration due to gravity, and Fa is the magnitude of the drag force. You account for...

struggling a bit in physics, if anyone can help me out soon, that'd
be great!!
3. In Lab #05 - Free Fall Motion, the time and position of a freely falling object are measured. The results are shown in Table 3. Assuming the position equation has the form of Y ) - Ata + Bt + C, (a) determine the function Y(t) by using the given data in Table 3. (b) Calculate the gravitational acceleration, g, and initial velocity....
please
show all work so i can double check my work and answer that i have.
Thanks.
a kt", k, n -1 are constants X P At t 0, P was located at xo and had a speed vo. Find the velocity and position of P as functions of time (and some or all of the parameters k, n, vo, Xo). Then, determine the special cases of your results for v, x corresponding to k αρ, m0.
A test model for a new type of braking system is designed to apply a braking force that decays following an exponential function. For an object moving in the (+) x direction (to the right), the force acts in the opposite direction. When the brakes are applied, the velocity change as a function of time in seconds can be approximated by . v=v(t) = V, e-At where Vo is a constant in [m/sec) and A is a constant in [1/sec)....
1 Vectors in Physics A particle is moving is such a way that its position after time t is described by the vector where t is measured in s. The particle has a mass of 2 kg. Report all answers in standard SI units. (a) What is the position of the particle at t = 0 and t = 1 s? (b) How far is the particle from the origin at t = 0 and t = 1 s? (c)...
PROJECTILE MOTION OBJECTIVE: The purpose of this lab is to study the properties of projectile motion. From the motion of a steel ball projected horizontally, the initial velocity of the ball ean be determined from the measured range. For a given initial velocity, the projectile range will be measured for various initial angles, and calculated by applying the theory for motion with constant acceleration BASIC PRINCIPLES: Projectile motion occurs when an object in a two-dimensional plane experiences motion only due...
