The boy of mass 40 kg is sliding down the spiral slide at a constant speed such that his position, measured from the top of the chute, has components r = 1.5 m, u = (0.7t) rad, and z = (-0.5t) m, where t is in seconds. Determine the components of force Fr, Fu, and Fz which the slide exerts on him at the instant t = 2 s. Neglect the size of the boy

none.

step-by-step explanation:

b=-1

find the slope and y-intercept of the second equation.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

i think it’s a i believe

●yes, this statement is absolutely apt.

hope this you
