James stewart, 2002 motorcross/supercross rookie of the year, is leading a race when he runs out of gas near the finish line. he is moving at 16 m/s when he enters a section of the course covered with sand where the effective coefficient of friction is 0.90. will he be able to coast through this 15-m-long section to the finish line at the end? if yes, what is his speed at the finish line?

continuous conducting path for current, power supply

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
