1) Force acting on the object is 6 N. The object is moving with acceleration of 3 m/s. When the object's acceleration is doubled, the net force would be, A) 3N B) 6N C) 9N D) 12N E) I8N 2) A push of magnitude P acts on a box of weight Was shown in the figure. The push is directed at an angle 0 below the horizontal, and the box remains a rest. The box rests on a horizontal surface...
1.A force vector, F, has components F angle, 0, of the force. 180 lbs and F, -60 lbs. Calculate the magnitude, F, and the direction 2. Calculate the resultant of the following 3 forces: F,- (100 N, 45 deg), F,- (80 N, 180 deg) and Fy-(140 N deg). In other words, calculate R, Ry, R, and 0R (Hint: Use the vector table to help with the procedure.) Vector Mag Dir х-сотропеnt у-соmponent Fi F3 R A 50 kg object is...

14 and 17 ty Recall that cos bt = (elb + e")/2 and that sin b1 = ( -e )/2i. In each of Problems 11 through 14, find the Laplace transform of the given function; a and b are real constants. Assume that the necessary elementary integration formulas extend to this case. 11. f(1) = sin bt 12. f(t) = cos bt 13. f(t) = eaf sin bt 14. f(t) = el cos bt
Problem 1: For each case, draw and label the forces (not components) acting on the object. Each arrow must start on the white dot and be straight. Then write one or more equations relating the forces on the object. Finally, rank the three forces in the blanks. Acceptable labels are Fw (or Fe or mg), Fx, F Fr, and Papplied Net Force Equation: Balanced Forces Equation: Rank the forces: Balanced Forces Equation: Balanced Forces Equation Rank the forces:_ Car slows...
Below you see four different situations and force diagrams for a circled system object for each situation. The first three involve an elevator. The fourth involves a box sliding over a smooth horizontal surface. In each case the initial velocity of the object is shown. Consider: How can you make sure the motion of the elevator/box is consistent with the given force diagram? (Hint: what is the direction of the sum of the forces in each force diagram?) Explain your...
x2-x+6 x3 +3x 7./Use the Apart command to decompose i into partial fractions. Question: which case is this?? Now find the antiderivative of each fractional expression by hand.

Any assistance to get me started with (b), (C), (d) , and (e) would be appreciated. Thank you! A system consisting of two pulleys, a spring, and four masses connected by strings is shown in the diagram below. Masses 1 and 2 rest on the side of a frictionless ramp at an angle θ from horizontal. mass 3 is suspended by a pulley, and mass 4 is hanging from a spring of spring constant k displaced a distance d from...
