The forces shown in the force vs. time diagram in the figure below act on a 7.5-kg particle. F, (N) 4 t (s) 1 2 3 4 5 -2 (a) Find the impulse for the interval fromt = 0 to t = 3.0 s. 12 V N.s (b) Find the impulse for the interval from t = 0 to t = 5.0 s. 1.6 Your response differs from the correct answer by more than 10%. Double check your calculations. N -s (c) If the forces act on a 7.5-kg particle that is initially at rest, find the particle's speed at t = 3.0 s. m/s (d) If the forces act on a 7.5-kg particle that is initially at rest, find the particle's speed at t = 5.0 s. m/s

A 600 gg particle moving along the xx-axis experiences the force shown in (Figure 1). The particle's velocity is 9.0 m/sm/s at xx = 0 mm.What is its velocity at xx = 3 mm?

A diver of mass 68 kg stands on a diving board 5.0 m above a pool. At the moment of the jump, the diving board transfers its 3400 J of energy to the diver, who leaves the board at an angle of 35°. a. What is the (total) speed of the diver just as they leave the diving board? b. What is the maximum height (relative to the surface of the water) of the diver? c. How long does it take for the diver to reach the surface of the water?

I'm trying to understand the different types of energies.  I understand the definitions, but when I apply them to situations, it doesn't make much sense to me. I have the following: A. Entrophy - measure of the amt of disorder, or randomness in a system B. Kinetic Energy - Energy in Motion C. Heat - kinetic energy contained in the random motion of atoms & molecules D. Chemical Energy - type of potential energy which arises from the arrangement of atoms and be release in chemical reactions E. Conservation of Energy: Kinetic to Potential Energy - its not possible to destroy or create energy F. Conservation of Energy: Potential to Kinetic G. Potential Energy - Energy an object has because of its location or structure   When I try to apply to the following, I come up with this: A: A Glass falls off the shelf & breaks B. An orange falling from a tree C. During exercise you get extremely hot. D Animals consume food (organic molecules) to make ATP to walk, breathe, etc. E. A large…
