As a fish jumps vertically out of the water, assume that only two significant forces act on it: an upward force F exerted by the tail fin and the downward force due to gravity. A record Chinook salmon has a length of 1.50 m and a mass of 50.5 kg. If this fish is moving upward at 3.00 m/s as its head first breaks the surface and has an upward speed of 6.50 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine the following. (a) the salmon's acceleration m/s2 upward (b) the magnitude of the force F during this interval N
two isotopes of carbon carbon-12 and carbon-13 have masses of 19.93 10-27 kg and 21.59 10-27 kg respectively. these two
Consider a binary star system in which the two stars have masses M1 and M2 and the stars move on circular orbits separated by a distance R
For nitrogen gas at 35 C calculate the vrms, the vp and the translational kinetic energy
A 10,000 kg empty railroad car moving at 3 m/s collides with a loaded railroad car weighing 196,000 N and couples with it
4.48 L of an ideal gas is initially at a temperature of 303oC. While the volume is kept constant, Determine the new temperature of the gas
An athlete performs a Romanian deadlift with 197 kg bar from floor to hips (0.75 m) in 2.1 seconds. How much mechanical power is generated from the athlete
For this question, I got 196 nC but apparently its -196 nC and i was hoping you could explain why the answer is negative: A styrofoam ball of mass 0.120 g is placed in an electric field of 6000 N/C pointing downward. What charge must be placed on ..
assuming the weight is evenly distributed.On a hot day in Las Vegas, an oil trucker loaded 37000 L of fuel. He encountered cold weather on the way to Utah, where the temperature was 23K lower than Las Vegas.
The electric field at a distance of 0.148m from the surface of a solid insulating sphere with radius 0.367m is 1690N/C, Calculate the electric field inside the sphere at a distance of 0.217m from the center
A hunter aims directly at a target (on the same level) 101m away. If the bullet leaves the gun at a velocity of 203m/s, by how much will it miss the target.
Because the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it should be released above the top of the loop-the-loop height.
A bolt on an engine is to be tightened with a maximum torque of 75 Nm. If a wrench has a length of 0.30 m, what is the maximum force perpendicular to the length that should be used to tighten the bolt?
