Answer: if this makes sense dx/dt = -1500 ft/sec
Explanation: The shadow is moving at a speed 1500 ft/sec towards
the point immediately below the ball. The high speed is to be expected
since initially the shadow is at infinity and has to move to the end
point in 1.76 seconds.
Answer:
64 J
Explanation:
W = ΔPE
W = mgΔh
W = (130 kg) (9.8 m/s²) (0.050 m)
W = 64 J
Answer:
false
Explanation:
u have to in order to understand better and correctly
Well momentum is = to Mass*Velocity so let's use an example to figure this out
If I weighed 50kg and I was jogging at 3m/s then I broke into a run at 6m/s how will me momentum be affected?
3m/s*50kg=150
6m/s*50kg=300
So as you can see by doubling the velocity you also double the momentum
