A brick of mass 1.5 kg slides down an icy roof inclined at 30.0° with respect to the horizontal. (a) If the brick starts from rest, how fast is it moving when it reaches the edge of the roof 1.75 m away? Ignore friction. m/s ? (b) Redo part (a) if the coefficient of kineti...
Thank you so much! :)
A cart starts from position 4 (which is 20m above ground) in the figure below with a velocity of 11 m/s to the left. Find the speed with which the cart reaches positions 1, 2, and 3. Neglect friction. speed at position 1 m/s? speed at position 2 m/s? speed at position 3 m/s? p...
standard form numbers are used around the world for....... 1:speed of light i need 3 more situations when you use standard form
A roller coaster has a loop the loop with a loop radius of 14.5 m. What is the minimum speed that the cart must have so that unconstrained riders do not fall out when the cart is upside down at the top of the loop? What condition on the riders is met at this speed?
the perimeter P of a square is four times the length of ones side s, or P=4s. Is (1455) a solution of this equation? If not, find a solution that uses one of the given values
A decroative floor pattern has one red square tile surrounded by 12 blue tiles. Write and evaluate an expression to show how many total tiles (red and blue) are needed if there are 15 red tiles. Then make a table showing the total number of tiles if there are 15,20,25, or 30 r...
