answer:
MAXIMUM SPEED
explanation:
IM SURE THAT IS THE ANSWER
Answer:
Explanation:
Speed is the distance covered over the time taken to do so.
s = d/t = 45 m / 3 s = 15 m/s
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
Answer:
The US Environmental Protection Agency (EPA) sets limits for exposure to x-rays and gamma rays in part because it recognizes that this form of radiation can cause cancer.
