A60 kg driver gets into an empty taptap to start the day's work. the springs compress 1.5ã10â2 m . what is the effective spring constant of the spring system in the taptap?

Place me with this question is my last question

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Mechanical energy is when there are no forces causing an object to lose energy. a. increased b. conserved c. decreased d. doubled i need this answer ! .
