Question

car is initially at rest on a circular track that has a radius of 40 m. The car then starts to move counter clockwise around the track, accelerating at constant angular acceleration of 1.0 rad/s². The time it takes for the car to move half of the way around the track is: (1) √6.28 s (2) √2.24 s (3) √3.14 s (4) √4π S​

Answer 1

Answer:

√6.28

Explanation:

1 rad/s2 in meter is 1/2pi then using the formula ac equals to delta thita/delta T ka hole square multiple with 40radius and divide by 2
