    A ball is thrown w/initial speed vi at an angle 𝜃i with the horizontal

    I apologize for that. a) \sqrt {\frac R g} Correct! b) {\sqrt {4gR}} \frac 2 Correct! c) \sqrt {gR} \frac 4 Correct d) The formula I used for the initial speed is this \sqrt {Vy^2+Vx^2}, and after I plugged in the information I got: (\sqrt {\frac {gR} 4}) +( \sqrt {\frac {4gR} {4}) = \sqrt...

    A ball is thrown w/initial speed vi at an angle 𝜃i with the horizontal

    A ball is thrown with an initial speed vi at an angle 𝜃i with the horizontal. The horizontal range of the ball is R, and the ball reaches a maximum height R/8. In terms of R and g, find the following. (a) the time interval during which the ball is in motion: Sroot(R/g) Correct (b) the ball's...

    Final velocity of the barbell dropped after a dead lift

    I was able to put all the pieces of the puzzle together. Thank you everyone for your help. As I navigate this course, I am learning that I should take breaks and return to the problem again and not spend 5 hrs working on problems without a break. Sometimes, I make some mistakes that don't make...

    Final velocity of the barbell dropped after a dead lift

    I did not convert cm to m. I'm sorry, I totally missed that part. For f. velocity, I got 11.33m/s

    Final velocity of the barbell dropped after a dead lift

    Eddie Hall is the current world record holder in the deadlift, a powerlifting maneuver in which a weighted barbell is lifted from the ground to waist height, then dropped. The figure below shows a side view of the initial and final positions of the deadlift. A side view of the initial position...

    How Can Returning Students Overcome Challenges in Online Physics Courses?

    Hello everyone! I am a returned student after 15 years of being out of school. Physics is very challenging for me, especially taking it in a different language. I like this forum because the instructors here don't just give the answers to the problems students ask, but they help the students...
