A mass of 2.5 kg lies on a frictionless table, pulled by another mass of 4.1 kg under the
influence of Earth's gravity.
The acceleration of gravity is 9.8 m/s2.
What is the magnitude of the acceleration
a of the two masses?
Answer in units of m/s2.

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
