019 (part 1 of 2) 1.0 points A 4.46 g bullet moving at 573.0 m/s pene- trates a tree trunk to a depth of 4.90 cm. a) Use work and energy considerations to find the magnitude of the force that stops the bullet. Answer in units of N. 020 (part 2 of 2) 1.0 points b) Assuming that the frictional force is con- stant, determine how much time elapses be- tween the moment the bullet enters the tree and the moment the bullets stops moving. Answer in units of s. 021 1.0 points Five ramps lead from the ground to the second floor of a workshop, as sketched below. All five ramps have the same height; ramps B, C, D and E have the same length; ramp A is longer than the other four. You need to push a heavy cart up to the second floor and you may choose any one of the five ramps.
