Question

You passed the salt and pepper shakers to your friend at the other end of a table of height 0.87 m by sliding them across the table. They both missed your friend and slid off the table, with velocities of 6 m/s and 2.4 m/s, respectively.

(a) Compare the times it takes the shakers to hit the floor.

= 1/1

i need part B

(b) Compare the distance that each shaker travels from the edge of the table to the point it hits the floor. (Compare only the horizontal distance d that each shaker travels from the table.)

Explanation / Answer

the times it takes the shakers to hit the floor is

t = root 2h/g

since intially both are at same height time remins same for both

tsalt =tpepper = 1:1

the formula for distance is d = u t

dsalt/dpepper = u salt/ u pepper = 6 m/s/ 2.4 m/s =2.5
