An object is projected from the surface of the earth with a speed of 2.72×104 m/s. What is its speed when it is very far from the earth? (Neglect air resistance.)

A child whirls a toy plane around in a circle of radius 60cm. She notices it takes 10s to make 12 complete rotations. Calculate: 1) The speed 2) The centripetal acceleration 3) The frequency of rotation 4) The period of rotation 5) The net force on the toy if the toy has a mass of 500g. 6) What force is responsible for the keeping the toy in rotation?

An orangutan leaps off of a cliff and its body begins to rotate clockwise. If the orangutan then starts to rotate both of its arms counter-clockwise, which of the following happens: The clockwise rotation of its body will be faster The clockwise rotation of its body will be slower The clockwise rotation speed of its body will not change Cannot say, not enough information provided

What is the angle in radians between the vectors a = (-9, 1,-10) and b = (10, -5, -5)? Angle: (rad (radians)

(a) Evaluate the gravitational potential energy (in J) between two 6.00 kg spherical steel balls separated by a center-to-center distance of 19.0 cm. (b) Assuming that they are both initially at rest relative to each other in deep space, use conservation of energy to find how fast (in m/s) will they each be traveling upon impact. Each sphere has a radius of 5.20 cm. m/s

Earth’s diameter is approximately 8000 miles. Estimate the speed of a point on Earth’s equator as it’s carried around with Earth’s rotation.

(a) Evaluate the gravitational potential energy (in J) between two 4.00 kg spherical steel balls separated by a center-to-center distance of 19.0 cm. (b) Assuming that they are both initially at rest relative to each other in deep space, use conservation of energy to find how fast (in m/s) will they each be traveling upon impact. Each sphere has a radius of 5.50 cm. m/s
