In the figure (0=52°, H1=0.23). Assuming a mass equal 0.2 kg starts from rest on the incline plane and finally stopped at the end of the horizontal line. If the rate of work done by the frictional force on the second surface until the mass stopped equal 5 Watt during 1.3 s. What is the distance d,? H1, d1 H2, d2 Select one: O 7.05 m 6.44 m 1.78 m 3.46 m 5.13 m

When a crate of mass m is dragged a distance d along a surface with coefficient of kinetic friction μk same path to its original position, the work done by friction is? 0 ○ +μ mgd О -μmgd ○ +2μmgd -2μmgd then dragged back along the

A 36 kilogram model rocket experiences an upward, position-dependent force due to its engine. The equation for this force is F = x^2 + 450 Find the work done by this force over the first 65 meters of vertical displacement. Find the speed of the rocket at this height of 65 meters. Assume that the rocket starts from rest and neglect any air resistance experienced by the rocket. The units for force are Newtons, and distance (displacement) is meters.
