A force of 23.1 N acts on a 10.0-kg mass in the positive x-direction, while another force of 10.7 N acts in the negative x-direction. The mass is initially at rest.
(a) Find the time rate of change o
A car drives for 20 miles total. The first 10 miles were at 30mph and the next 10 miles were at 50 mph. What is the average speed? Thank you.-avg speed = total distance/total time
we know the total d
An electron of mass 9.11*10^-31 kg leaves one end of a TV picture tube with zero initial speed and travels in a straight line to the acceleration grid, which is a distance 2.6 cm away.It reaches the g
Two particles of mass m1 = 1.7 kg and m2 = 3.5 kg undergo a one-dimensional head-on collision as shown in the figure below. Their initial velocities along x are v1i = 15 m/s and v2i = - 7.5 m/s. The t
E = (1/2) mv^2 = (mv)^2 / (2m = p^2/2m
=> p = √(2mE)

How do you calculate speed given the acceleration of 4.5 x 10-3m/s2 and a time of 18 mins?-From (See sources below)
Formula: v = v0 + at
Where: v = velocity (speed), v0 = initial velocity, a = accele
The peregrine falcon is the fastest bird, flying at a speed of 200 mi/h. Nature has adapted it to reach such speed by placing baffles in its nostrils to prevent air from rushing in and slowing it. Als
A daredevil is shot out of a cannon at 45.0° to the horizontal with an initial speed of 30.0 m/s. A net is positioned a horizontal distance of 51.0 m from the cannon. At what height above the cannon s
Hello everyone,
Im in an intro to physics class and Im having trouble with the following questions:
A spring initially has no mass attached (far left in the figure above). When a mass (m1) is attach
Tom the cat is chasing Jerry the mouse across a table surface 1.5 m off the floor. Jerry steps out of the way at the last second, and Tom slides off the edge of the table at a speed of 6.0 m/s. Where
What equation(s) do I use? The original question is A car initially at rest travels a distance of 30.0 m in 8.0 s with uniform acceleration. Determine the magnitude of the acceleration of the car (in

A silver dollar is dropped from the top of a building that is 1362 feet tall.
For answers on a, b, and c are all correct, but I cant figure out how to find part d. If you could expla
A stone is dropped from the top of a cliff. It hits the ground below 4.2 seconds after being dropped. How high is the cliff?
i allready know that Accleration-9.8initial velocity is 0 and time is 4.2
Here is the problem:
To start an avalanche on a mountain slope, an artillery shell is fired with an initial velocity of 310 m/s at 47.0° above the horizontal. It explodes on the mountainside 35.0 s a
A 4.0 kg block is put on top of a 5.0 kg block. To cause the top block to slip on the bottom one while the bottom one is held fixed, a horizontal force of at least 8 N must be applied to the top block
