Question
If two bicyclists move around a circular track of radius 100 m, at the same speed. m/s. but in opposite directions, then they have equal size accelerations, 1 m/s^2. they have opposite accelerations. +1 m/s^2 and -1 m/s^2. one has centripetal acceleration of 1 m/s^2 and the other has centrifugal acceleration of 1 m/s^2 they might have different accelerations, depending on whether they have identical mass or not. Earth's gravity attracts a person with a force of 120 lbs. The force with which the Earth is attracted towards the person is zero. small but not zero. billions and billions of tons. 120 lbs. Which of the following is NOT a vector? Acceleration. Weight. Mass Velocity. All of these choices are correct. A cyclist races around a circular track at the constant speed of 20 m/s. The radius of the track is 50 m. The acceleration of the cyclist is zero. 8 m/s^2. toward the center of the track. 10 m/s^2. downward. 20 m/s^2, in the direction of travel. If a ball at the end of a string is whirled in a vertical circle at constant speed, the tension will be the same throughout the motion. greatest at the lowest point in the motion. greatest at the highest point in the motion. greatest at a point where the string is instantaneously parallel to the ground.Explanation / Answer
1] A, they have equal size of acceleration.
Both cyclists have centripetal acceleration of v^2/r = 100/100 = 1 m/s^2
