Mass of 25 kg weight is 25/9.81 slug of mass.
Answer: the brand of paper towel
Explanation: the independent variable is the one you control in an experiment. the dependent variable would be the amount of water in the paper towel
Answer:
a = 3.27 m/s²
T = 275 N
Explanation:
Given that:
Mass m₁ = 42.p0 kg
Mass m₂ = 21.0 kg
Consider both masses to be in a whole system, then:
The acceleration can be determined as:

Making acceleration the subject in the above formula;




a = 3.27 m/s²
in the string, the tension is calculated using the formula:



T = 274.68 N
T ≅ 275 N
Can't really plot a graph here for question 1.
2a) The car speeds up from A to B. The car travels at a constant speed from B to C. The car slows down to a stop from C to D.
b) From the graph, at 10 seconds, the car is moving at 20 m/s.
