Two cars A and B are stopped at a traffic light, waiting for the light to change from red to green, see Figure 3. Car B is 6 meters behind car A. When the light changes to green, car A leaves accelerating at a rate of 0.3 m / sec2, while car B departs 2 seconds later and accelerates at a rate of 0.8 m / sec2. Determine the position where they are next to each other, measured from the “o” point.
Three roofers are at the edge of a flat roof a distance h above ground level. One throws a ball vertically downward at a speed vi; at the same time, the second throws a ball vertically upward at the same speed, and the third watches all this in amazement. What is the time interval between when the first ball strikes the ground and the second ball strikes the ground? (Use the following as necessary: g, h, and vi.)
A ball is suspended from a light 1.4 m string as shown. The string makes an angle of 28 degrees with the vertical. The ball is then kicked up and to the right such that the string remains taut the entire time the ball swings upwards. This kick gives the ball an initial velocity of 1.1 m/s. What will be the speed, in meters per second, of the ball when it reaches its lowest point (θ = 0)? What will be the maximum angle, in degrees, the string will make with the vertical?
As a loaded train is going up a ramp of α = 3 degrees as shown in the figure, the freight wagons behind are disconnected from the locomotive and the wagons start to run downwards. If S= 2180 meters below, there is a station. In order not to have a major accident at the station, it will be informed and the road will be directed to an empty line. How much time is there for this? So in how many seconds will the wagons be at the station? What will be its speed when it arrives at the station? The tonnage of the empty wagons is W=120 tons.
A stone is thrown vertically upward from the ground with a velocity of 48.3ft/sec. One second later, another stone is thrown vertically upward with avelocity of 96.6 ft/sec. How far above the ground will the stones be at thesame level?The car is traveling at 48 km/h when the traffic light 90 mahead turns yellow.

The figure below shows a diver going through general motion. The diver's center of gravity can be assumed to undergo a projectile motion. Assume that the diver takes off from a diving board such that his center of gravity is a height ho = 11m above the water level and enters the water at a horizontal distance 1 = 4m from the end of the board. If the total time the diver remains in the air is t2 = 2.3s, calculate the speed, vo, and angle of takeoff ,O, of the diver's center of gravity. Also determine the height, hi, the diver reaches at the top of the dive. (Note that tr is NOT half of t2.)

The motion of block E shown in the figure is harmonic and is defined by the equation yE =0.15 sin10t, where yE and t are expressed in meters and seconds, respectively. The constant of R1 is 150 N/m and the constant of R2 is 250 N/m. The mass of the bars that support the 15 kg body W is considered negligible. Find the stable solution that describes the motion of the system. (The image is from above)
