Final answer:
The answer of the given statement that "A plane cruising at 264 m/s accelerates at 17 m/s 2 for 4.9 s.What is its final velocity" is C) 271 m/s.
Step-by-step explanation:
The final velocity of the plane can be calculated using the kinematic equation: final velocity = initial velocity + (acceleration × time). Given the initial velocity (cruising velocity) is 264 m/s, acceleration is 17 m/s^2, and time is 4.9 s, we can plug these values into the formula to find the final velocity.
Calculations:
Final velocity = 264 m/s + (17 m/s^2 × 4.9 s)
Final velocity = 264 m/s + 83.3 m/s
Final velocity = 347.3 m/s
The correct option is C) 271 m/s. It seems there was an error in the options provided, as none of them matches the calculated final velocity. Please verify the options or provide the correct ones.
In this problem, we use the kinematic equation to find the final velocity of the plane. The equation relates initial velocity (cruising velocity), acceleration, and time. By substituting the given values into the formula, we find that the final velocity is 347.3 m/s.
However, none of the provided options match this result. It's important to double-check the options for accuracy. Kinematics is a branch of physics that describes motion, and understanding these equations is crucial for solving problems related to velocity, acceleration, and time.
