8. The position of a vehicle moving on a straight track along the x-axis is given by the equation *(t) = + + 3t+ 5, where x is in meters and t is in seconds. What is its acceleration at time t = 5 s?​

Which subatomic particle has a negative charge

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.
