A car traveling 85 km/h strikes a tree. The driver finally comes to a stop after traveling 0.8m. What was the average acceleration of the driver during the collision? Please try and explain the proces
Im just looking for the formulas, thank you in advance!-speed = distance/time
so: distance = speed x time
acceleration, a = (change in velocity)/(time)
though you can use, a = (change in speed)/(cha
If anyone could help me with these problems it would be greatly appreciated, Ive tried to do them but I dont get how I can set up the equation with enough variables to make it work.

Two X-ray diffraction angles 8.9 and 18.0 are measured for the first two orders from a particular crystal. Explain why from these two pieces of information you cannot determine either crystal spacing
Please explain if possible how to get the answer because Im not sure how to do this problem.-the skid mark tells you how far the car traveled once braking was initiated
use vf^2=v0^2 + 2ad
vf=final
Someone please explain this to me... I dont know why Im confused. Why is the equation for velocity for a free falling object v = gt if it is being dropped from something. g has units of m/s and t has
Why is it advantageous to have the fundamental standards such as time and length be accessible invariable indestructible and reproducible?-reproducible:
With a predefined process, you can reproduced t

Question is asking if Vx = 5.3 units and Vy=-8.9 units, determine the magnitude of V>
Second question is asking the direction of V>
Thanks big help-V = sq. root ( Vx^2 +
A man kicks a ball from ground level with an initial velocity of 8.0 m/s at an angle of 30 above the horizontal.
What is the maximum height of the ball above the ground?
How far from the man will th
A satellite with a mass of 500kg is placed in an orbit (5) times the radius of the earth (6.37 * 10^6)(5). calculate the force experienced by the satellite.
I think I need the equation F = MV^2 / Rbu
is there anyone out there who is clever possibly with a good qualification and doesnt agree with a=v^2/r please say hail and get in contact with me asap thanx-it sometimes does not make sence-It somet
I need some help with this Physics Integrated Exercise(IE). [An IE is a two part exercise. The first part typically requires a conceptual answer choice based on physical thinking and basic principles.
A car starts from rest at a stop sign. It accelerates at 3.0 m/s2 for 5.0 s, coasts for 2.1 s, and then slows down at a rate of 2.3 m/s2 for the next stop sign. How far apart are the stop signs? (The
The QB launches a pass into the end zone, 60 yards (54.86m) away, where a receiver is waiting to make the catch. Suppose the QB throws the ball at 55mi/h (24.59m/s). At what angle to the horizontal mu
