WebThe equation for change in thermal energy is: ΔE = m x c x Δθ Change in thermal energy = mass x specific heat capacity x change in temperature ΔE = Change in thermal energy (J); m = Mass (kg); c = Specific heat … Web0m = 100m + (15m/s) (10s) + 0.5a (10s)^2 -100m = 150m + 50s^2a -250m = 50 (s^2)a a = -5m/s^2 Now to the answer. The velocity as the rock reaches the ground will be greater than the initial velocity. Just try substituting values to test this out. v_f = v_i + at v_f = 15m/s - 5m/s^2 (10s) v_f = 15m/s - 50m/s v_f = -35m/s speed_f = v_f

WebA system is an object or group of objects. There are changes in the way energy is stored when a system changes. For example: • an object projected upwards • a moving object hitting an obstacle • an object accelerated by a constant force • a vehicle slowing down • bringing water to a boil in an electric kettle Web11.1 Temperature and Thermal Energy; 11.2 Heat, Specific Heat, and Heat Transfer; 11.3 Phase Change and Latent Heat; Key Terms; ...
