One of the limiting factors in high-performance aircraft is the acceleration to which the pilot can be subjected without blacking out; it’s measured in “gees,” or multiples of the gravitational accele
An object is thrown downwards with a speed of 10m/s from a cliff that is 120m above ground. If air resistence is negligible, determine the time taken to reach the ground.-x = ut + (1/2)at^2
x = displ
A 30 N force is applied to a spring with spring constant k = 220 N/m.
How much does the spring stretch?-Equation: F=kx
x=F/k
x=30/220
x=.1364 meters-30N * 1m/220N = 3/22 m
If a neutral metal rod were placed in a parallel plate capacitor, would the rod swing towards one of the charged plates?
I understand that the rod would be polarized, but would electrons within the r
The minimum distance required to stop a car moving at 30.0 mi/h is 48.0 ft. What is the minimum stopping distance for the same car moving at 56.0 mi/h, assuming the same rate of acceleration?
Thank
Doing a projectiles lab. We didnt actually learn angular velocity but Im to provide a factor for any inaccuracy in our lab, which was to roll a steel ball from an angled ramp. What I got so far is fri
A car is slowing down. What is the acceleration if the speed BEFORE slowing down was 14.76 m/s and it comes to rest in 39.308m?
I would really appreciate the help ASAP!
Thanks!-use the equation Vf^2=V
I have 3 different forces all with different directions
one is 424 at east
one is 400 at north
and one is 194 at west
how do i combine them?-You have 1 east and 1 west, so (424 - 194) = net 230 east
A ball is thrown horizontally from the top of a building 18.2 m high. The ball strikes the ground at a point 83.2 m from the base of the building. The acceleration of gravity is 9.8 m/s.

Two wooden crates rest on top of one another. The smaller top crate has a mass of m1 = 18 kg and the larger bottom crate has a mass of m2 = 95 kg. There is NO friction between the crate and the floor,
The Sun is considered to be a satellite of our galaxy, the Milky Way. The Sun revolves around the center of the galaxywith a radius of 2.20x10^20 meters. The period of one revolution is 2.50x10^8 year
