Explanation Given data: V = 4 m 3 Formula used: Write the Archimede’s principle equation. F b = ρ V g (1) Here, F b is the buoyant force, ρ is the density, V is volume, and g is the acceleration due to gravity, which is known as 9.8 m s 2 . As the buoyant force needs to be about the same magnitude as the weight force, so compute the weight force on the balloon by assuming its mass of the displaced air. From graph, consider the maximum density that is ρ = 1.2 kg m 3 . Substitute 4 m 3 for V , 1.2 kg m 3 for ρ and 9

Car A starts from rest at t = 0 and travels along a straight road with a constant acceleration of 6 ft/s^2 until it reaches a speed of 60ft/s. Afterwards it maintains the speed. Also, when t = 0, car B located 6000 ft down the road is traveling towards A at a constant speed of 80 ft/s. Determine the distance traveled by Car A when they pass each other.Write the solution using pen and draw the graph if needed.
