- A rectangular solid has length L=12.6 mm, width W=23.8 mm, and height H=32.5 mm. Find the length of a diagonal AB from the upper left rear vertex to the lower right front vertex. Round the answer to 1 decimal place.A hiker start from his parked car and walked as follows : 12km due east followed by 8km at 40 north of east , followed by 10km due . Find the components ( along east and north of the net displacement and the magnitude and direction of the displacementA child exerts a force of 27 N on the handle of a small wagon. If the handle of the wagon is directed upwards 20° from the horizontal, find the amount of work done in moving the wagon 20 m horizontally. Round to the nearest N⚫m. The amount of work done is approximately N⚫m.

By what factor does the area increase when the length of the leg is increased by a factor of 6? A factor of 36 O A factor of 12 O A factor of 12k O A factor of 36kHow much force must be applied to a 1.8kg ice hockey puck to give it an acceleration of 10 m s-2Calculate the force (in Newtons) required to push a 50kg wagon up a 0.2 radian inclined plane. One Newton (N) is equal to 1 kg-m and the g2 force due to gravity on the wagon is F = m * g, where m is the mass of the wagon, and g is the acceleration due to gravity (9.8 ). Please ignore friction in this problem. Hint: draw a picture, and express the forces on the wagon as vectors. Force N
- A hydraulic jack has input piston with diameter 0.38 m and output piston with diameter 1.39 m. If the input force is 659 N, calculate the output force in kN. F = kNA wagon is pulled 80 feet using a force of 40 pounds applied to the handle, which makes a 60° angle with the horizontal. Use a dot product to calculate the work W done. w = foot-pounds (Round to the nearest whole number.)(5) A force T is applied at the tip of the rod as shown. If the n- component of the force is T, = 35 lb, determine the t-, x-, and y-components of the force T. The t-axis is directed along the rod, and the n-axis is perpendicular to the rod. Ans: T₁ =-130.6 lb, Tx=-103.6 lb, Ty = -86.9 lb T n 40° O 55°
