you need to specify the units for velocity. assuming that the velocity is in metres per second, the wavelength is 2 metres

.02 what? And are we talking money or weight?
A train is traveling up a 3.9 degrees incline at a speed of 3.15m per s when the last car breaks free and begins to coast without friction. How long does it take for the last car to come to rest?
the answer in the back of the book is 4.7 sec and i just can't figure it out I don't get how the book got 4.7 seconds. I got .02 seconds because v=vo+at or velocity= initial velocity + acceleration *time. Thus, -.2/-9.81= .02 seconds. Vinital=3.15m/s A=gsin(3.9) V=0 0=3.15m/s+9.81m/s^2*sin(3.9)t So, -3.15m/s/(.667m/s^2)=t t=-4.7
A 20 kg box is lifted to a 4.0 m shelf if it falls what is its velocity as it reaches the floor?
if: v = final velocity, u = initial velocity, a = acceleration, s = distancethen: v2 = u2 + 2asThis is just one of the different formulae you could choose to use, but the advantage of this one is that you don't have to calculate time taken before the calculation can be done. The mass of the box (20kg) is not needed, as all objects will accelerate at the same rate unless wind resistance is significant. Unless the box has a parachute or very large surface area, this shouldn't be a complication.u = 0a = 9.8 ms-2 (acceleration due to gravity)s = 4 mv2 = 02 + 2*(9.8 ms-2)*(4 m)v2 = 78.4 (ms-1)2v = sqrt(78.4) ms-1v = 8.9 ms-1
What is the force exerted by a cather's glove on a 0.15-kg baseball moving at 35ms that is stopped in 0.02 s?
First, multiply mass x velocity, to get the momentum.The momentum in this case is also equal in magnitude to the impulse, which is the change of momentum - since all the momentum gets canceled. Since impulse is also time x force, you can divide the momentum, or impulse, by the time, to get the force. Due to the units used, the answer will of course be in newton.

zero
A wave travels at 3 ms along a spring toy If the wavelength is 02 m what is the waves frequency?
Frequency = speed / wavelength = 3/0.2 = 15 Hertz
What is the period T of a wave whose Frequency is 5.0 Hz?
T = 1/f T = 1/(50 Hz) = .02 sec
