Q.2 Dynamics of a system can be divided into kinematics and kinetics. To analyse thedynamic of the system, accelerated motion of a body will be considered.(a) State the difference between kinematics and kinetics?(b) Briefly describe the differences between rectilinear motion and curvilinearmotion? Provide drawings in your answer to describe the motion.(c) Car A is initially starting from rest and travelling along a straight road with aconstant acceleration of 5 ms-2 until it reaches a speed of 50 ms-1 as shown inFigure Q.2(c). Afterwards, this speed is maintained. At the same time, car B isinitially travelling towards A at a constant speed of 30 m/s(i) Draw v-t graphs for both cars A and B. In both graphs tabel ti which is thetime just before the cars passing by each other.(ii) Find the distance travelled by car A when it reaches a speed of 50 m/s(iii) Express the equation for disuance travelled in term of ti for car A when ittravels in a constant speed of 50 m/s and for car B when it travels in aconstant speed of 30 m/s.(iv) Calculate the distance travelled by car A when it pass car B.30 km/sВ9 kmFigure Q.2(c)

A skier slides straight down an incline of 25 degrees without using her poles. The slope itself is 96 meters long, and the skier starts from rest at the top. What would the velocity of the skier be at the bottom of the incline if friction can be neglected? What would your answer be to the previous question if the coefficient of kinetic friction between the skis and the snow is 0.13 on the incline? Upon reaching the bottom of the incline in part b, she reaches a flat portion, and decides to just let friction slow her to a stop. How far does the skier travel along the horizontal portion before coming to a stop, if the coefficient of kinetic friction is 0.28 on the flat portion?
A 2-stage rocket is fired from rest. Its acceleration data are shown in the graph below. Plot the v-t and s-t graphs describing the motion of the rocket-clearly showing the shape of the curve (or add a note) and values at inflection points. Show any calculations as well. Then find the velocity of the rocket and its elevation after 20 seconds of flight. a (m/s?) 25 18 (s) 15 20
You have put a sonar device at the top of a frictionless inclined plane, as shown in the diagram below. That device allows you to measure the distance an object is from the device, as well as the speed and the acceleration of that object. If we decide that the origin (h = 0) is at the sonar device, we want to know what the height change is as we slide down the incline. 0 For an angle below the horizontal of 6.46, we see that our object has slid a distance 1.13 m, as measured along the incline itself. Calculate the height change in meters - and report your answer as a negative number. (This value would be useful for calculating the change in gravitational potential energy, as we will do in the lab.) h=o 10% O i 26 QUATU 99+ hp X 55 83°F 3:11 PM 10/16/2022 Ctrl 0
For each of five trials, find the acceleration from ax= (twice distance glider moves)/(time squared) The glider & hanging mass have the same acceleration, and we will call to the left the +x direction for the glider, and down the +x direction for the hanging mass. Using Microsoft Excel, plot a graph of the acceleration vs. the size of the hanging mass. Make sure the graph contains all of the features it should. This graph should have points that follow a straight line. Add a linear trendline to the graph and also display the equation for this line on the graph. We can show that Newton’s Laws predict that the acceleration should be ax=m2g/m1+m2 (3) where m1 is the glider’s mass and m2 is the amount of hanging mass. Equation (3) tells us that the predicted slope of your a x vs. m2 graph should be equal to g/(m1+ m2). Calculate the predicted value of the slope, and then find the percent error between it and the experimental value of the slope. When you do the % error calculation,…

At t=0 an object has a position of 1 m and has a steady velocity of -2.5 m/s. If this were a cart on a very long track, would it be going right or left? Using position = initial position + vt, what will be the object’s position at t = 4 seconds?
