Equations of Motion Worksheet 1. A car moving at a velocity of 25 m/s‚ accelerates at a rate of 6 m/s2. Find its velocity after 3s. 2. An object is dropped from rest. Calculate its velocity after 2.5s if it is dropped: a. On Earth‚ where the acceleration due to gravity is 9.8m/s2. b. On Mars‚ where the acceleration due to gravity is 3.8m/s2. 3. A motorbike is travelling with a velocity of 3m/s. It accelerates at a rate of 9.3m/s for 1.8s. Calculate the distance it travels in this time. 4. A Tesla

In Chapter 14 which is Kinetics of a Particle : Work and Energy‚ the objectives that I learnt are I knew the concept of a conservation of energy to solve the kinetic problems. Besides‚ I would be able to develop and apply the principle of work and energy that

Company X Problem Analysis Through extensive analysis from the customer satisfaction surveys‚ and research from the satisfaction task force‚ Company X found three major problems areas. The company’s programs reflect poor quality‚ the development times are taking longer than the projected due dates and a small portion of employees are discrediting the company name and values. Each of these problems has contributed to the main problem; the increasing rate at which Company X is losing customers

a rotating turntable. The different vectors representing velocity for the travelling marble are shown below. Notice that the size of the vector remains the same but the direction is constantly changing. Because the direction is changing‚ there is a ∆v and ∆v = vf - vi ‚ and since velocity is changing‚ circular motion must also be accelerated motion. vi ∆v vf -vi vf2 If the ∆t in-between initial velocity and final velocity is small‚ the direction of ∆v is nearly radial (i.e. directed

acceleration of -1.5m/s2. What is the final velocity of the car? How far does the car travel in this time interval? vf = vi + a(Dt) or vf = (0 m/s) + (-1.5 m/s2)(5.0 s) = -7.5 m/s Dx = vi(Dt) + 1/2a(Dt)2= Dx = (0)(5.0 s) + 1/2(-1.5 m/s2)(5.0 s)2 = -18.75 m or -19 m (sig figs). 2E 1.

and observed. This kind of mechanism is very commonplace in machines. Machines are made up of a number of parts and relative motion between the various parts permits the working of the machine. As the crank is rotated the rod starts moving but the velocity is not uniform. It is greater towards one direction than the other. This principle is utilized extensively in some machines. Aim Understand the relative motion of the rotational and sliding joint. Understand the movement of the rotational and

Creating a bigger problem. The ride is bumpy‚ the tires are wearing down wrong‚ the fuel mileage is poor‚ the engine has more strain on it due to rough driving and the height of the car is drooping down‚ causing unsafe wear on the inner wheel wells‚ while also creating a risk of a blown tire.
