A5.3: A car is moving along a straight road. Its position is given by the function s(t)=-2+2t+5 meters, where t represents time in seconds. Find the difference in the velocity of the car between t=2 seconds and t=5 seconds.

A car moves along a straight line. The car starts to move from Thi- Qar toward Baghdad with a constant velocity of 120 km/hr, compute the following: 1- If you know the car needs 3 hrs to reach out to Baghdad, What is the total displacement between Thi-Qar and Baghdad? 2- what is the value of the constant acceleration?

WORKSHEET: A racing car starts at rest at point A and increases its speed around the track at a constant rate of 6 ft/sec², traveling counterclockwise. Determine the position and the time at which the car's acceleration magnitude reaches 20 ft/sec². y ↑ 200 ft Used with permission from "Engineering Mechanics: Dynamics." McGill/King, 4th Ed, 2003

Q5: A point initially at rest moves along the x-axis. It is acceleration varies with time as a= (5t+6) m/s?. IF it starts from the origin, the distance covered by it in 2 second is : 18.66 m 14.33 m 12.18 m 6.66 m

A locomotive, starting from rest, is uniformly accelerated up to a maximum speed, taking 1 min and travelling a distance of 0.5km. It then runs at maximum speed for 2 min and finally is uniformly retarded for 30 s to bring it to rest. Find the maximum speed. And sketch a velocity-time graph and find the total distance travelled.

2- find the center of mass, the velocity of the center of mass, the momentum, and the kinetic energy of the following system: do f(xd) xaf] m₁ = 1 kg T₁=1+2j+3 k v₁ = 2î+3ĵ m₂ = 1 kg T₂ = 1-j+ k v₂ = 2) + 3k

1. The wheel starts rotating from rest, 5) if its angular velocity W as a function of angular position is w=0.2-0², where 0 is in radian, and its radius ris 0.3 m, what is the magnitude of the total linear acceleration (in m/s2) of point P after the wheel has turned 1.4 revolution(s) from rest. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Your Answer: Answer P

Q1. The image below shows an example of "absolute dependent motion analysis", where the motions of two objects depend on each other, and the goal is to find the relations in their motions (i.e., in their positions, velocities, and accelerations). Please put the suggested steps of analysis in the correct order. VA A B VB Differentiate the entire equation with respect to time, and extract the relation in velocities. Repeat for acceleration if needed. Set up a coordinate (s) along the direction of motion from a fixed point (O) or a fixed datum line. Represent the positions of the objects respectively. In some cases intermediate objects need to be considered too and their positions need to be represented as well. Recognize the constant length(s) and find the depending geometric relations between the position variables.
