Kinematics question .

a pilot is flying from montreal, a displacement of 571 km [e 13.0(degrees) n]. the airplane is capable of flying at 301 km/h in still air. during the flight there is a constant wind of 95 km/h blowing form the direction of [e 30.0(degrees) n]. assuming she flies directly to montreal, (along the displacement vector) calculate the plane's speed relative to the ground and the direction the pilot should point the airplane to maintain his direct route to montreal.

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap

Awoman holds a book by placing it between her hands such that she presses at right angles to the front and back covers. the book has a mass of m = 1.8 kg and the coefficient of static friction between her hand and the book is μs = 0.67. no attempt 50% part (a) what is the weight of the book, fgb in newtons?
