Laws of motion 2

Physics

force= dP/dt

change in momentum= 2mv= 2(0.25)10

time= 0.01

force= 5/0.01 = 500N

B) 2s

angular velocity of death well so that object does not slide

root g/uR

Formula for conical pendulum

tan0= v²/Rg

sin0= r/L

r=radius from centre to ball

L= length of string

Bowl problem formula

same as conical pendulum

length of string= radius of bowl

tan0= v²/rg = w²r/g

acceleration of monkey relative to rope

If object is released from inclined plane then acceleration along vertical plane or y axis

a= gsin0 along inclined plane

acc along y plane= a sin0

so a_y = g sin²0

if block A is falling from inclined plane A of 30^o, and block B is falling from an inclined plane B of 60^o, then relative acceleration of A wrt B
