A piece of meat is thrown vertically upward, and a falcon is released at the same time. The piece of the meat reaches the maximum height after 2.26 seconds.
Find the initial velocity of the meat [2 marks]
How many seconds does it take to reach the maximum height? [2 marks]
Find the total time when the falcon catches the meat at a height 13.0 m while the meat is falling [2 marks]
A 12 kg trolley moving at 6.5 m/s is slowed down to 2.5 m/s in 12 m by applying some force. What is the net force applied to the trolley? [3 marks]
128 N force is needed to just start 25 kg block moving across the floor. Determine the coefficient of static friction. Draw FBD. [3 marks]
A 27 kg crate is pulled along the horizontal surface by a force of 85 N as shown. The coefficient of friction between the two surfaces is 0.23. Draw FBD.
Find the horizontal and vertical components of force. [1 mark]
Find the normal force [2 marks]
Find the friction [1 mark]
Find the horizontal acceleration of the crate [2 marks]
Find the time taken to move the crate by 12 m considering it starts from rest [2 marks]
