A rugby player is tackled by another player and lands with the combined weight of both players on his knees. If the weight of the first player is 1300N and the tackler is 1100 N, and the player’s knee measures 0.1 m by 0.1 m, then 240,000Nm2 of pressure is exerted on the turf when the player lands on both his knees. Is this a realistic figure for the amount of pressure? Explain your answer.
