A dog running in an open field has components of velocity Vx= 1.8m/s and Vy=-2.5m/s at time t1= 11.9s. For the time interval from t1= 11.9s to t2= 24.5s, the average acceleration of the dog has magnit
An electron in a TV picture tube is accelerated through a potential difference of 1.0 multiplied by 104 V before it hits the screen. What is the kinetic energy of the electron in electron volts?

I know that relativistic mass increases as velocity increases, but why?-we, as humans, cannot because we dont have the technology to go that fast, this is a very complex subject and to save myself tim
A marble slides without friction in a vertical plane around the inside of a smooth, 26 cm-diameter horizontal pipe. The marbles speed at the bottom is 3.5m/sthis is fast enough so that the marble make
...on a string of circular cross section depends on the tension in the sting, T, the radius of the string, R, and its mass per volume, p.-Mass/unit length ρ = p*πR²
v = √[T/ρ] = √[(m*a)/(m/L)] = √[L*
Airodinamicaly, it is imposible for it to fly.-Hi:
it spelled Aerodynamically and Yes they can -Due to fact there wings can generate more lift than gravity can hold them down ( basically it you can
If the coefficient of kinetic friction between tires and dry pavement is 0.800, what is the shortest distance in which an automobile can be stopped by locking the brakes when traveling at 28.5 m/s?-No
Party stores sell small tanks containing 44gof helium gas.

gravitational potential energy = mgh
m=mass
g=gravitaional field strength (9.81)
h=height
mass has to be in kg
g is in Nkg^-1
h= has to be in metres
all has to be standard units-mgh if the heights
