Don't know what I am doing wrong
An adventurous dog 7.50 kg dog runs onto a frozen, frictionless pond with an initial velocity of 4.31 m/s along the positive x-axis. The dog slides across the ice while being pushed by a steady wind with a force of 16.1 N in the positive y-direction. What is...
there is no other way to find a new velocity it just takes me back to square one...I keep on getting 0.372 grams for my mass of rope...which other way can I find velocity
I did exactly what you are telling me and I am not getting the answer. I am doing M=ukmg*L\v*squared and ukmg is my Force tension that I calculated. These are my values that I am putting in
uk= 0.2000
m= 53.6 kg
g= 9.8
v= 1.14
L=4.60
It seems like a very easy question but I don't know...
Oliver (m=90.0 kg) uses a 4.60 m long rope to pull Jordan (m=53.6 kg) across the floor (μk=0.200) at a constant speed of 1.14 m/s. Jordan signals to Oliver to stop by "plucking" the rope, sending a wave pulse forward along the rope. The pulse reaches Oliver 149.0 ms later. What is the mass of...
When a bullet traveling at 721 m/s strikes a block of wood originally at rest on a frictionless surface, the bullet emerges from the other side of the block of wood traveling at 349 m/s. If the mass of the bullet is 5.38 g and the mass of the block is 744 g, what is the speed of the block after...
I am having trouble with this question, I know what I need to find, just don't know what route to take.
A 53.0 g tennis ball with an initial speed of 30.5 m/s hits a wall and rebounds with the same speed. The figure below shows the force of the wall on the ball during the collision. What is...
