7. show your work The crate, which has a mass of 100 kg, is subjected to the action of the two forces. If it is originally at rest, determine the distance it slides in order to attain a speed of 6 m/s. The coefficient of kinetic friction between the crate and the surface is uk 0.2. 1000 N 800 N 30
need a nice and clear answer thank you
KINEMATICS AND KINETICS OF A PARTICLE Problem 1 (15 Pts.) The 2.3 Mg (Mega grams) mine car is being pulled by the winch M mounted on the car. If the winch exerts a force of F (367t2) Newton on the cable, where t is in seconds, determine the power output of the winch when t - 12 s, starting from rest. The crate, which has a mass of 232 kg, is subjected...

The crate has a mass of 80 kg and is being towed by a chain which is always directed at 20° from the horizontal as shown. If the magnitude of P is increased until the crate begins to slide, determine the crate's initial acceleration if the coefficient of static friction is p0.5 and the coefficient of kinetic friction is px 0.3.

Question 6 2 points Save Answer A box of mass m = 2.04 kg is attached to a spring (see figure). The spring constant is ks = 200 N/m, but the friction coefficient uk between box and surface is unknown. When the spring is stretched by a distance Xo = 0.400 m relative to its relaxed position and then released (from rest), the spring contracts so that the box is again momentarily at rest when the spring is most squeezed,...
