5 A block with a mass, mi = 2.5kg, sits a distance d = 85cm from the top of a frictionless ramp at an angle, B = 30°. The mass is at rest and pressed against a spring (k = 1600N/m) compressing it 15cm. At t = 0, the mass is released. a. Calculate the change in gravitational potential energy from t = 0 to the time that the mass fırst stops touching the spring. d OMO b. Calculate the kinetic energy of the mass when first stops touching the spring. c. Calculate the speed of the mass when it reaches the end of the platform. d. Calculate the velocity of the mass when it reaches the end of the platform.
