Hello ^___^ Please help me! Thank you very very much! Determine if the planes are parallel. [x,y,z] = [1,2,2] + s[0,-1,0] + t[0,0,1] [x,y,z] = [1,0,-3] + s[0,0,1] + t[-1,0,0] thank you ^__^Y

Thanks you for your quick reply. I really appreciated it, although I still cannot find the way to get the answer which is 7,086.7 N.

A car that weighs 15,000 N is initially moving at 60 km/hr when the brakes are applied. The car is brought to a stop in 30 m. Assuming the force applied by the brakes is constant, determine the magnitude of the braking force.

-2y+3y = -21 y(-2+3)= -21 y(1)= -21 y = -21 + (-1) y = -21 - 1 y = -22
