A car is merging onto the expressway with an acceleration of 1.77 m/s^2. When it begins down the ramp the car is traveling at a speed of 11.1 m/s. How long will it take for the car to reach a speed of 24.4 m/s

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.

Acar travels 40m in 8 seconds find the car speed
