Fill in the boxes and use a calculator to determine how long it would take each machine to travel 60 miles (in minutes). Use the
speeds you previously calculated in miles per hour for each machine. Round answers to the nearest tenth (one decimal place). NASCAR car = Thrust SSC car = TGV Train = Spirit of Australia Boat = Lockheed SR71 Airplane =

Answer:
Explanation:
Given that:
mass of stone (M) = 0.100 kg
mass of bullet (m) = 2.50 g = 2.5 ×10 ⁻³ kg
initial velocity of stone () = 0 m/s
Initial velocity of bullet () = (500 m/s)i
Speed of the bullet after collision () = (300 m/s) j
Suppose we represent to be the velocity of the stone after the truck, then:
From linear momentum, the law of conservation can be applied which is expressed as:
∴
The magnitude now is:
Using the tangent of an angle to determine the direction of the velocity after the struck;
Let θ represent the direction:
