Question

What force did the ball apply to the glove 2., When an m-kg bird lands midway on between two poles, a distance d apart. 1ight telephone wire the wire sags smeters. How much tension does the bird produce in the wire? An m-kg piece of wood is sandwiched between two other t . The coefficient of Er 3. and held in place by a clamp etween the boards is lamp o siip out when held vertically? . What must be the minimum force on each of the two outer boards if the middle board A diver of mass m jumps from a board d above the downward motion is stopped t seconds after he er, what average upward force did the water exert

Explanation / Answer

2)X-component

f=ma

T cos5degree=0

so the x component wont matter

3)the force acting download mg+n

the minimum fricitional force to hold the back in position is fr where

fr=2*u*N

where N is normal force

fr=2*u*N=mg+N slove for N.

Y-component

f=ma

Tsin5degree-mg=0

Tsin5degree=m*9.8

Tsin5degree=9.8*m

T=9.8*m/sin5degree.
