Answer:
no
Explanation:
the inertia of an object does not make it to come to rest, this is normally caused by friction
250 kg*m/s
Momentum is found by multiplying mass by velocity
25*10=250
F=g(m1*m2)/r^2
gravitational force is directly proportional to product of masses and inversely proportional to square of distance between them.so consequently mass should increase and distance should decrease
Force can be calculated by the product of mass and the acceleration of the object in motion. Acceleration is the change of velocity per change in time. The expression would be:
F = ma
where
a = Δv/Δt
The object is from rest and time 0. Acceleration would reduce to:
a = v/t
F = m(v/t)
2000 = 100 (v / 0.3)
v = 6 m/s -------> OPTION 1
Answer:
Speed= 10meters per second, Frequency = 4hz
Explanation:
First we need to find the frequency of the wave. The formula for frequency is: f (frequency) = 1 / T (period). This means we need to convert the period into seconds and then use it as a denominator with one on the numerator.
Since the period is 0.25,
1/0.25= 4hz
Now, we just need to multiply the frequency with the wavelength
4hzx2.5= 10
= 10 meters per second
