- In the figure below, a 2.9 kg block is accelerated from rest by a compressed spring of spring constant 644 N/m. The block leaves the spring at the spring's relaxed length and then travels over a horizontal floor with a coefficient of kinetic friction uk = 0.25. The frictional force stops the block in distance 8.1 m. What was the original compression distance of the spring?Hoe do scientist define mass in terms of kilograms?A 1000N force accelerates a sports car from 33.0 m/s to 38.0 m/s in the direction of the force. If the distance covered by the sports car is 173 m, calculate the sports car’s mass.
