Please answer in 15 mins /ASAP A 3-kg block has a speed of v= 4 m/s at point O as it travels along a rough incline OA withHK-0.25. It then hits a spring with k-500 N/m at point A and eventually comes to atemporary stop. Let x be the deformation of the spring when the block reaches atemporary stop.v = 4 m/s02 m-6.91(2+ x)6.91(2+ x)-6.91(2/sin 20 + x)6.91(2/sin 20 + x)20°A4. Which of the following gives the correct expression for the WORK DONE BY FRICTIONon the object as it goes from O to the lowest point reached by the block?ng is the closest to the DEFORMATION OF THE SPRING, x, when thest point and temporarily stops?

A 3-kg block has a speed of v= 4 m/s at point O as it travels along a rough incline OA with HK=0.25. It then hits a spring with k=500 N/m at point A and eventually comes to a temporary stop. Let x be the deformation of the spring when the block reaches a temporary stop. v = 4 m/s APUNT -6.91(2+ x) 6.91(2+ x) -6.91(2/sin 20 + x) 6.91(2/sin 20 + x) 0 2 m 20° A 4. Which of the following gives the correct expression for the WORK DONE BY FRICTION on the object as it goes from O to the lowest point reached by the block? ng is the closest to the DEFORMATION OF THE SPRING, x, when the st point and temporarily stops?
