Two forces F1 and F2 act on a 9.20-kg object. F1 = 30.0 N and F2 = 12.0 N.
Determine the magnitude and the direction of the acceleration if the angle between F1 (horizontal line) and F2 (slanted lin

Here it is:
You toss a ball straight up in the air, it goes up, comes down, and you catch it. If it took 5.6 seconds from when you threw it to when you caught it, how high did it go?

People hoping to travel to other worlds are faced with huge challenges. One of the biggest is the time required for a journey. The nearest star is 4.1 E 16 m away. Suppose you had a spacecraft that co
I cant get a straight answer for this question to save my life! Help me! PLEASE!!! Gahhhh :P-Because atoms as a whole are neutral! So if they contain negatively charged particles, they must also conta
In the film 2001: A Space Odyssey, a space station in the shape of a large wheel rotates at a rate sufficient to produce an apparent gravitational acceleration equal to 9.80 m/s2 (see figure). Find th
We had a physics lab where we threw a softball into the air and measured the time in seconds only.My time was 2.51 seconds (in total it took the ball from release until it hit the ground).
Questions:
figure skater A has a mass of 44.9 kg and pushes figure skater B away from herself with an acceleration of 3.5 m/s^2. figure skater B has a mass of 70.1 kg. the magnitude of the acceleration of figure
A typical household circuit is capable of carrying 30.0 A of current at 120 V before the circuit breaker will trip. How many 1500-W hair dryers can run off one such circuit?-1500/120 = 12.5 A per drye
A particles trajectory is described by x=(1/2t^3-2t^2) m and y=(1/2t^2-2t) m, where t is in s.
So what is the the trajectorys direction at t=0 and at t=4? Measure it as an angle from the x-axis-x=(1/
