Exercise 4 Question 1 A 20 kg concrete block falls off of a scaffolding on a building site, hits a pile of sand and comes to a standstill within 10 ms. The average net force of the sand and other forces on the concrete block is 10 500 N upwards. Take upwards +. 1.1 Calculate the impulse of the net force on the concrete block. 1.2 Calculate the velocity at which the block hits the sand before it comes to a standstill. 1.3 Calculate the height of the scaffolding. 1.4 Calculate the total time from when the block starts to fall until it comes to a standstill. 0000 DOO
