An object is thrown downward with an initial
speed of 3 m/s from a height of 59 m above
the ground. At the same instant, a second
object is propelled vertically up from ground
level with a speed of 36
...with respect to the ground. If the base of the ladder is moved 0.51 m away from the wall, how far will the top of the ladder go down?-The ladder forms a rt triangle with the wall
hypotenuse = 4.4

Shouldnt it move towards the outside, due to centrifugal force?-I found this one fascinating.The ekman pumping doesnt explain it.According to Wikipedia the Ekman pumping is a property of the spherical
A tractor/trailer truck on a 7% downgrade (road slanted at 4 degrees below the horizontal ) is limiting its acceleration to 0.3m/s per second by braking. If there were no breaks on the 10000kg trailer
A 1500kg elevator is moving downward, and its speed is increasing at the rate of 1.3m/s per second. Find the tension in the supporting cable?-(9.8 - 1.3) = net acceleration of 8.5m/sec^2 down.
Force =
Please help!
A truck is stopped at a stoplight. When the light turns green, it accelerates at 2.5 m/s2. At the same instant, a car passes the truck going 15 m/s. Where and when does the truck catch u
How do neutrons contribute to an atom? Just mass??-The neutrons make the protons stick together.Otherwise, the protons would fly apart from each other because they all have the a positive charge.
Im not the best at rearranging equations and I dont know how to isolate for mass 2 if you have it on both sides
Show work plzz 10 points best answer thanks-Hmm, lets see, well we can divide both side
A speedy tortoise can run with a speed of 10 cm/s and a hare can run 20 times as fast. If they both start atthe same time but the hare stops to rest for 2 minutes. The tortoise wins by a shell (20 cm)
What is the acceleration of an object that changes velocity from 10 m/s to 20 m/s over a span of 2 seconds?
A. 50 m/s^2
B. 5 m/s^2
C. 5 m/s
D. 6 m/s^2-A = change in velocity minus time
Change in velo

Hi theres a question thats been bugging me lately:
Lets say we throw a ball vertically upwards, If we assume that the only forces acting are Upthrust, Drag (frction due to air resistance and weight m
