its B
what about the cubic root what do we have to do with it ?
the derivative of e^f(x)= e^f(x) . d/dx [f(x)] therefore y'=e^3x.3 2) use chain rule y'=1/6(x^2)^-1/2 . 2x
the derivative of e^f(x)= e^f(x) . d/dx [f(x)] therefore y=e^sinx = e^sinx . cosx
ki is the kinetic energy initial how much energy is there in the system in the form a speed at the beggining of the collision as you know there are two forms of mechanical energy ( kinetic energy and potential ) when the object is moving it has kinetic
1 month = 4 weeks (18 x 15 ) x 4= 1080 $
linear momentum p=mv lets say m1 =0.1 kg m2=0.4kg before collision pi=(m1. u1)+(m2 . u2) pi=(0.1 . 100) + ( 0.4.50) = 30 when they collide together pf= (m1+m2)vf since linear momentum is always conserved pi=pf pf= (m1+m2)vf =pf (0.1+0.4) vf = 30 vf=60m/s
Draw a free body diagram with the force of 20N and with Fn and with fg and then find the acceleration with newton second law . When you find the acceleration you can plug it into kinematics equation : vf=vi+at to find final velocity
