Determine the speed (m/s) of the plane such that the plane and the satellite have the same centripetal acceleration.

A race car starts from rest on a circular track of radius 632m. The car’s speed increases at the constant rate of 0.690m/s^2. At this point where the magnitude of the centripetal and tangential accelerations are equal, find the following A) the speed of the race car m/s B) the distance traveled M C) The elapsed time s

The figure below shows an object initially at point A traveling in the +x-direction. It turns in a circular path at constant speed until it is traveling in the +y-direction at point C. The quarter-circle arc from A to C is 245 m in length, and the particle moves from A to C in 38.0 s.

The earth rotates once per day about an axis passing through the north and south poles, an axis that is perpendicular to the plane of the equator. Assuming the earth is a sphere with a radius of 6.38 x 10 m, determine the speed and centripetal acceleration of a person situated (a) at the equator and (b) at a latitude of 65.0 ° north of the equator

An airplane is flying north. It makes a gradual 180° turn (at any instant, the turning angle is less than 90°) at constant speed of 472.2 km/h, changing its direction of travel from north through east to south in 38 s. The centripetal acceleration of the plane for this turn in m/s? is: Answer:

A scooter, starting from rest, accelerates at 2.72m/s^2 on a circular track with a 205m diameter. What is the elapsed time, in seconds, at which the centripetal acceleration of the scooter has the same magnitude as its tangential acceleration?

A ball on the end of a string is whirled around in a horizontal circle of radius 0.254 m. The plane of the circle is 1.31 m above the ground. The string breaks and the ball lands 2.16 m away from the point on the ground directly beneath the ball’s location when the string breaks. The acceleration of gravity is 9.8 m/s2 . Find the centripetal acceleration of the ball during its circular motion.
