Textbook Question

Chapter 3, Problem 17MCQ

A person jumps from a wall and lands stiff-legged. Which statement best explains why the person is less likely to be injured when landing on soft sand than on concrete?

a. The concrete can exert a greater force than the sand.

b. The person sinks into the sand, increasing the stopping distance.

c. The upward acceleration of the person in the sand is less than on concrete, thus the force that the dand exerts on the person is less.

d. b and c

e. a, b, and c

the cable may break and cause severe injury. cable is more likely to break as compared to the [1] ds, inclined at angles of 30° and 50° to the vertical rings by way of a scaled diagram. [4] I 30° T₁ 3cm 3.8T2 cm 200 N 50° at it is headed due North and its airspeed indicat 240 km/h. If there is a wind of 100 km/h from We e relative to the Earth? [3]

Can you explain this using nodal analysis With the nodes I have present And then show me how many KCL equations I need to write, I’m thinking 2 since we have 2 dependent sources
