1.- Captain John Stapp pioneered research into the physiological effects of large accelerations on humans. During one such test his sled slowed from 282 m/s with an acceleration of -201 m/s2. Part A How long did it take him to stop?

A car traveling 95 km/h strikes a tree. The front end of the car compresses and the driver comes to rest after traveling 0.90 m .

A) What was the magnitude of the average acceleration of the driver during the collision?

B) Express the answer in terms of "g's," where 1.00g=9.80m/s2.

3.- part A If Vx = 9.8 units and Vy = -6.4 units, determine the magnitude of V⃗ .

Express your answer using three significant figures.

Part B Determine the direction of V⃗ .

Express your answer using three significant figures.

    Deriving centripetal acceleration (shortened) For no apparent reason, a poodle is running counter-clockwise at a constant speed of 4.90 m/s in a circle with radius 2.9 m . Let v⃗ 1 be the velocity vector at time t1, and let v⃗ 2 be the velocity vector at time t2. Consider Δv⃗ =v⃗ 2−v⃗ 1 and Δt=t2−t1. Recall that a⃗ av=Δv⃗ /Δt. Hint: It may be helpful to assume that at time t1, the poodle is on the x-axis, i.e., that...
