Academics

Q. The springs of a 1500 car compress 5.80 when its 61 driver gets into the driver's seat. If the car goes over a bump, what would be the frequency of vibrations?

Q. A baseball pitcher throws a fastball at a speed of 35m/s. The acceleration occurs as the pitcher holds the ball in his hand and moves it throughout an almost straight-line distance of 3.7 m. estimate the acceleration, assuming that it is constant and uniform.
