Need help

There must be a net force toward the center of the circle in order for an object to have centripetal acceleration. True False If an object has a tangential acceleration of 3.0 m/s^2 and a radial acceleration of 4.0 m/s^2. what is the magnitude of the acceleration of the object? Give your answer without unit. For an object moving on a curved path, the concept of circular motion still applies We just need to find the effective radius (called the radius of curvature) at any point on the curved path. True False Centrifugal force is what cause a twilling ball to fly off when the string breaks. True False

Explanation / Answer

Question 5:

Answer: True

Question 6:

Answer:

acceleration = sqrt(arad2 + atan2) = sqrt(3.0^2+4.0^2) = 5.0m/s^2

Question 7:

Answer: True
