Answer:
Work done = 3750 Joules
Step-by-step explanation:
The force acting in the body should be resolved to it's horizontal component before we can use ut to solve for the problem
Horizontal component= 150 * cos 60
Horizontal component= 150*0.5
Horizontal component= 75N
Work done= Force * distance
Work done= 75*50
Work done= 3750 Nm
Work done = 3750 Joules
"<span>Terrance trains at the rate of 6 miles every half an hour and Jesse trains at the rate of 2 miles every 15 minutes. How long will each person take to run of a total of 50 miles at the given rates?"
I will treat this as two problems: Terrance's case and Jesse's case.
Terrance's rate is (6/.5) mph, or 12 mph, and Jesse's is (2/0.25) mph, or 8 mph.
At this rate, Terrance can run 50 miles in how many hours? Divide 50 miles by 12 mph: (50/12) hours, or (25/6) hours, or 4 hours 10 minutes.
At his won rate, Jesse can run 50 miles in (50 mi) / 8mph hours,
which reduces to 25/4 hours, or 6 1/4 hours.</span>
now, let's take a peek at the denominators, so we have "3" and "x-4" repeated, so we'll use them only once in our LCD, so using those repeated factors once, our LCD boils down to 3(x-4)(x+3).

Answer:
Length of arc AB is,
= 2πr (angle between AB) /360
=2×3.14×90/360
=1.57 cm
