A1700 kg car moving at 5.1 m/s is initially traveling north in the positive y direction. after completing a 90° right-hand turn to the positive x direction in 4.1 s, the inattentive operator drives into a tree, which stops the car in 240 ms. what is the magnitude of the impulse on the car (a) due to the turn and (b) due to the collision? what is the magnitude of the average force that acts on the car (c) during the turn and (d) during the collision? (e) what is the angle between the average force in (c)and the positive x direction?

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s
