The contact force between two objects during the first few seconds of contact is given by F(t) = 300(t^2 + 2t) Newtons, with time (t) in seconds. Find the magnitude of the impulse experienced by either object over the first 1.5 seconds. Draw the free-body diagram that goes with the problem. Thank you.

The bumper of a car has a force sensor mounted inside which records the force vs time graph during crash testing. A particular collision occurs between t = 0.075s and t = 2.32s and can be modelled by the following function: F(t) = 4t4 – 80t² + 140t – 10 A graph of the collision is also provided below: Impulse 60 50 40 30 20 10 1 time (s) Part A The impulse during the collision will be while the maximum force experience by the bumper will be 75 kg · m/s, 33N 54 kg · m/s, 54N O 75 kg · m/s, 54N 54 kg · m/s, 33N (N) aɔ10

The forces shown in the force vs. time diagram in the figure below act on a 2.8-kg particle. F, (N) 4 t (s) 3 4 5 -2 (a) Find the impulse for the interval from t = 0 to t = 3.0 s. N:S (b) Find the impulse for the interval from t = 0 to t = 5.0 s. N:S (c) If the forces act on a 2.8-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 2.8-kg particle that is initially at rest, find the particle's speed at t = 5.0 s. m/s 2.

An insurance company is testing air bag safety. Car A has front air bags and Car B does not. In both cases, the cars are driven into a brick wall with the same momentum. In Car A, the dummy survives, but in Car B, the dummy does not. In terms of impulse and force, please explain this result. The dummy in Car B experienced a greater impulse and a greater force than in Car A. O The dummy in Car B experienceda greater impulse but the same force as in Car A. The dummy in Car B experienced the same impulse but a greater force than in Car A. O The dummy in Car B experienced the same impulse and the same force as in Car A. O Not enough information to determine.
