A motorcycle accelerates at 10 m/s2 to reach a final velocity of 50 m/s from rest. How much time passed during the acceleration?

The four giant gas points that are made primarily of lightweight elements are

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.

Can you match these to the correct definition
