is not moving. Knowing that P starts from rest, and its speed increases at a
constant rate of 5 mm/s', determine (a) the magnitude of the acceleration
when t=6 s, (b) the time for the magnitude of the acceleration to be 90 mm/s².

A woman rides a carnival Ferris wheel at radius 18 m, completing 4.8 turns about its horizontal axis every minute. What are (a) the period of the motion, and the magnitude of her centripetal acceleration at (b) the highest point and (c) the lowest point? (a) Number i Units (b) Number i Units (c) Number i Units
A bicyclist is at the bottom of a hill with a speed of 30 ft/s. After traveling 600 ft on the road, she reaches the top of the hill with a speed of 15 ft/s. Her total acceleration at the top of the hill is 1.3 ft/s^2. Assuming her acceleration along the road is constant. -What is the radius of curvature for the top of the hill?
How would I begin to solve this problem? In Example 2.6, we considered a simple model for a rocket launched from the surface of the Earth. A better expression for a rocket's position measured from the center of the Earth is given by y(t) = (RE3/2 + 3*(g/2)1/2 REt)2/3 where RE is the radius of the Earth (6.38 ✕ 106 m) and g is the constant acceleration of an object in free fall near the Earth's surface (9.81 m/s2). (a) Derive expressions for vy(t) and ay(t). (Use the following as necessary: g, RE, and t. Do not substitute numerical values; use variables only.)
A Ferris wheel with radius 8.5 m initially rotates clockwise at a constant rate by completing 1.25 rev in 40.00 s. It then begins to decelerate at a rate of 0.40 rad/s2 with its only passenger at the top of the wheel. Find the direction of the total acceleration vector. Express your answer as a positive number with respect to the positive x-axis. Choose up and to the right as your positive direction.

The earth moves around the sun in an orbit that is roughly circular with a radius of 1.5 x 10^11m once every year (1 year = 3.15 x 10^7s). What is the magnitude of the acceleration experienced by the Earth?
