If you are asked to determine an objects speed, what information must you have? A: distance and period of time B: distance and direction C: period of time and direction D: distance and change in position

Consider two closed systems A and B. System A contains 3000 kJ of thermal energy at 20°C, whereas system B contains 200 kJ of thermal energy at 50°C. Now the systems are brought into contact with each other.

What is the maximum and minimum resultant possible from a 20-N force and 4-N force?

Velocity is the rate at which an object moves in a certain direction. what would cause a change in velocity?

The position of an object is given by x = at3 - bt2 + ct, where a = 4.1 m/s3, b = 2.2 m/s2, c = 1.7 m/s, and x and t are in SI units. What is the instantaneous acceleration of the object when t = 4.1 s?
