Homework Statement On Earth, an astronaut and equipment weight 1,960.0 N. While weightless inspace, the astronaut fires a 100 N rocket backpack for 2.0 s. What is the resulting velocity of the astronauts and equipment? Homework Equations ? The Attempt at a Solution t=2.0 s w=mg...

That's true. Thank you so much! I truly appreciate it! =]

hi! would this one be it? v= u +at and then resulting to be 24.5.

Homework Statement A rock thrown straight up climbs for 2.50 s, then falls to the ground. Neglecting air resistance, with what velocity did the rock strike the ground? Homework Equations well we are looking for v=? we have: t=2.50 s and g=9.8 ^do we need gravity? yes, right? =S...

wow! thank you so much! i truly appreciate it!

oh so then it is 30km/h?

hm, but it is asking for kilometers per hour. gosh sorry I'm soo ugh for this.

ooh so then its the same..

ok no..that doesn't make sense :S

oh so then i multiply that times 2? or would i do 15.0/60?

Homework Statement A boat moves 15.0 km across a lake in 30.0 min. What was the average speed of the boat in kilometers per hour? Homework Equations average speed: d/t The Attempt at a Solution ok since it is asking kilometers per hour that is the part tha confuses me. i mean i...

Homework Statement A cubic tank holds 1,000.0 kg of water. What are the dimensiosn of tank i meters. Homework Equations n/a The Attempt at a Solution ok so its a cube therefore its six sides. do you use the lateral? ahh i am so lost... i am sorry the profesor gave us...

oooh, yeah I got it now. thanks.

Homework Statement A sled pulled out a constant velocity across a horizontal. If a is a horizontal force of 8.0 x 10^1 N is applied at an angle of 53 degrees in the ground. What is the force of friction between the sled and the snow? Homework Equations I convert the N into grams...

hehe thanks, I got it! thank y'all so much.
