Question 7 (1 point) Listen The figure below shows a block of mass 2 kg resting on a rough incline and connected to a spring of negligible mass and spring constant 100 N/m by a massless string which runs over a frictionless pulley. The block is released from rest when the spring is at its relaxed length and travels 20 cm down the incline before it comes to rest. The coefficient of kinetic friction μk between the block and the incline is k = 100 N/m www 2 kg 37° 0.50
Listen axis under - A particle of mass 2 kg moves along the x the influence of a single force ₹ = (3x² − 4x + 5)î where x is in metres and F is in Newtons. If the speed of the particle is 5 m/s when the particle is at x 1 m, find the speed of the particle when it is at x = 3 m. 8.7 m/s 4.3 m/s 6.7 m/s 2.8 m/s 10.9 m/s
