Answer:
Yes, there will be collision.
Explanation
Initial relative velocity u = 34-5.4 = 28.6 m/s
required final relative velocity v = 0
Acceleration , suppose be a .
Distance traveled =d = 160 m
Using the formula for relative motion,
v² - u² = 2as
0 - 28.6²=2as
a = - 2.55 m s⁻².
Since this required value is more than maximum braking deceleration so , there will be collision.
Nicolaus Copernicus was considered the <span>"Father of Astronomy" because he believed the earth was the center of the solar system. The rest of the choices do not answer the question above.</span>
Answer:
Explanation:
The translational kinetic energy depends on the mass and speed of the body, as follows:
While rotational kinetic energy depends on the moment of inertia and the angular velocity of the body, as follows:
. We know that:
Replacing (1) in (2):
Answer:
Clara has speed of 80m/min
Explanation:
Clara was jogging at 600 m in 5 minutes. She stopped suddenly which reduced her velocity and then she waited for 10 minutes so that her friends comes near her. She stopped to catch her friend. During this 10 minutes the velocity of Clara is zero. She started to walk again at a slower speed of 80m/min.
