To escape a grizzly attack, a black beardoes what its enemy cannot do: It climbs a tree whose trunk has a small diameter. If themass of the black bear is 140Kg, calculate: a) The weight of the black bear.b) The work done by the black bear in climbing 18 m up a tree.2. Thomas put on his big-pack of weight 120N. He then starts running on level ground for100m. After 100m, he started to climb up a ladder of 10m.a) How much work was done on the pack while on the level ground?b) How much work is done from climbing the ladder 10m?c) What is the total amount of work done by Thomas?3. A 250kg crate slides 5.2m across a surface. The coefficient of friction on the surface is0.40. Calculate the work done by:(a) friction(b) gravity4. A world-champion weightlifter does 5.0 x 103 J of work in raising a weight from the floorto a height of 2.0m. Calculate:a) The average force exerted to lift the weightble%2:

Here , the work done by the Bear is equal to the net change in gravitational potential energy of…
