I know i need to use a simple vector diagram ...but I'm not sure how to set it up...
In what direction should a boat point if it has a speed of 10 m/s, and wants to end up directly across a river with a current of 5 m/s.
help? :confused: :bugeye: :rolleyes:
Help please--multiple choice
Two identical blocks are lifted at constant velocity by ropes that run over frictionless pulleys, as shown in the diagram. Block B is raised twice as fast as Block A. The magnitudes of the forces are respectively FA and FB, while the power supplied is respectively...
10) A 5 kg ball sits motionless at the edge of a 2m long 1.2m tall table. A cube of mass 0.5kg plows into it head-on at a speed of 26m/s
There is a graph below in the attachments about the collision.
a) Determine the total impulse given to the ball. b) Determine the velocity of the...
An object collides elastically (perfectly) with another object (identical object) at rest. If it is not a head on collision how can i PROVE that the angle between them afterwards is 90 degrees? :confused: :bugeye:
I have NO IDEA on what to do...it's been puzzling me and my friends for a...
A Man dragged a 51 Kg bag at a 45 degree angle with a force of 400 N. The bag moved along hte pavement with a constant speed. What is the coefficient of static friction?
OK SO, you can make a triangle and figure out that 283 N are pulling horrizontal and 283 pulling vertically. But I am not...
Thanks, I think that I understood that really well...but a similar question is:
A spaceship is observed traveling in positive x direction with a speed of 150 m/s when it begins accelerating at a constant rate. The spaceship is observed 25 s later traveling with an instantaneous velocity of...
the acceleration in problem 1 is the acceleration during the period of time when the rocket is on--not when it has been turned off...
btw, thanks a lot for the help with the other one but
t=S/(V1+V2)...where did you get 1 for S...did you just use it as 1 unit? and why does the t become 1/t?
OK---a rocket is launched at 53 degrees above horizontal with an initial speed of 100 m/s. It moves along its initial straight line path with an acceleraqtion of 30 m/s^2 for 3 seconds. At this time, the rocket is turned off and it proceeds to fall as a free body.
how can i find,A) the...
