Question

A mass of 2 kg lies on a frictionless table, pulled by anothermass of 3.3 kg under the influence of Earth's gravity. Theacceleration of gravity is 9.8 m/s2. What is themagnitude of the acceleration a of the two masses? Answer in unitsof m/s2. b.) T, a and g represent positive quantities. Which equationis correct? 1. T-(3.3kg)g=(2kg) a 2. (3.3kg)g-T=(2kg) a 3. T- (3.3 kg)g=(2kg + 3.3) a 4. T+(2kg)g= (3.3kg) a 5. (3.3kg)g - T=(2kg+3.3kg) a 6. (3.3kg) g- T=(3.3kg) a 7. T- (2kg)g= (3.3kg) a 8. T- (2kg)g=(2kg) a A mass of 2 kg lies on a frictionless table, pulled by anothermass of 3.3 kg under the influence of Earth's gravity. Theacceleration of gravity is 9.8 m/s2.
