Ok, here is the prob.
You are arguing over a cell phone while trailing an unmarked police cruiser by 25m; both you and the cruiser are traveling at 110km/h. Your argument diverts your attention from the police cruiser for 2.0s (long enough to look at the phone and yell "I won't do that!"). At...

riru, just in case u missed that,
knowns
960n force up
.504 m/s^2 acceleration
n=kg*m/s^2
960n=?kg*(.504+9.8)---->to accelerate upwards, the force is the upward velocity, plus gravity, since that is being overcome.
thus, you have 93.2kg patient (mass)
w=mg
so 93.2kg*9.8m/s^2=913n
riru, i hope u read this this morning. IVE GOT IT. ok, so here goes
w=mg
thus 5lbs=m*(9.8m/s^2)
since 5lbs is not ci units, convert, using the ratio that 1n=.2248lb
the conversion turns 5 lbs into 22.24n
22.24n=m*(9.8m/s^2)
due to the nature of n (kg*m/s^2), you can divide out g...
Finding weights on other planets URGENT
yeah, here comes a homework problem my class had that both me and my friends couldn't get. please help us :bugeye:
A bag of sugar weighs 5.00 lb on earth. what should it weigh in Newtons on the moon, where the free-fall acceleration is 1/6 that of...
Here is the question
To lift a patient, four nurses grip the sheet on which the patient is lying and lift upward. If each nurse exerts an upward force of 240n, and the patient has an upward acceleration of .504 m/s^2, what is the patients weight.
answer: 913 N
HOW DOES THIS WORK. THANKS
