Answer:
They are both equal
Step-by-step explanation:
60 stays 60, and -60 converts to 60, so they are both 60
60=60

Answer:
|F net| = 20.22 N
θ ≈ 19.8°
Step-by-step explanation:
F net = 15N i + 8cos(60°)N i + 8sin(60°)N j
= 15N i + 8×½N i + 8×√3/2N j
= 15N i + 4N i + 4√3N j
= 19N i + 4√3N j
|F net| = √(19²+(4√3)²) = √(361+48) = √409 ≈ 20.22N
tan(θ) = 4√3 ÷ 19 ≈ 0.36 → θ ≈ arctan(0.36) = 19.8°
The answer is b 14/3.
Hope this helps!

Answer:
3.33 meters per second
Step-by-step explanation:
you must find the total time that Mr. B spent to complete the swim and bike.
Information:
0h 25' 10'' ---------> Swim
1h 30' 50'' ---------> Bike
he spent 1h 55' 60'', this is 1h 56'.
now you must substract this time from the record time to find the time alloted to run:
first you convert both times into minutes:
now substracting:
so he must travel 10 km in 50 minutes, that is:
speed = distance/time
1 km is equal to 1000 meters and 1 minute is equal to 60 seconds.
so Mr.B's speed must be 3.33 meters/sec
