A Review | Constants Part A A 57.0 kg crate of tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it, and the crate just begins to move when your force exceeds 313 N. Then you must reduce your push to 208 N, to keep it moving at a steady 25.0 cm/s. What are the coefficient of static and kinetic friction between the crate and the floor? Enter your answers numerically separated by a comma....

Review Constants | Periodic Table Part A On your first trip to Planet X you happen to take along a 295 g mass, a 40-cm-long spring, a meter stick, and a stopwatch. You're curious about the acceleration due to gravity on Planet X, where ordinary tasks seem easier than on earth, but you can't find this information in your Visitor's Guide. One night you suspend the spring from the ceiling in your room and hang the mass from it. You...

part B- now you try leaning more horizontal so that your feet
get closer and closer to slipping against yhe floor. what is the
smallest angle Theta relative to the ground that you could lean
without slipping?
ML Ice wall You are pushing against a wall while your body is slanted, as shown. Stylish! The wall is made of smooth ice and so has essentially zero friction. The floor, however, is made of rough sandstone and so has coefficients of...

< 9 of 13 Review Constants Periodic Table Part A A calorimeter contains 28.0 mL of water at 11.0 °C. When 250 g of X (a substance with a molar mass of 60.0 g/mol) is added, it dissolves via the reaction X(s) + H2O(1) X(aq) and the temperature of the solution increases to 30.0 °C. Calculate the enthalpy change, AH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that...

Problem 1 (American football) For the purposes of this problem, neglect air re- sistance. Suppose that you and your friend are playing catch with a football of mass m at some distance D apart from each other, as shown in the figure below FI (a) (5 points) At first, your friend is nice and throws the ball to you exactly where you r friend throws the ball from some height H above the ground at are. Assuming you some anglefro...

Suppose a small compact car with a mass of 1000 kg is traveling
north on Morewood Avenue at a speed of 15 m/s. At the intersection
of Morewood and Fifth Avenues, it collides with a truck with a mass
of 2000 kgthat is traveling east on Fifth Avenue at 10 m/s. It’s
now 2 seconds after the collision has occurred. Fortunately, all
occupants were wearing seat belts and there were no injuries, but
the two vehicles became thoroughly tangled and...
