Ablock of wood, which is 12.0 cm long, is dropped through an infrared sensor designed to measure the time that the sensor is blocked. assuming that this block of wood blocks the sensor for a time interval of 0.27 seconds, what is the speed of this block as it passes through the sensor? is this speed âaverageâ or âinstantaneousâ?
can u me with this ?

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.
