Answer:
When a heavy football player and a light one run into each other, does the lighter player really exert as much force on the heavy player s the heavy player exerts on the light one. Yes. The interaction between the two players, the force each exerts on the other have equal strength.
Answer:
31-40 m/s
Explanation:
The kinetic energy of an object is given by :
m is mass of the object
v is velocity
If mass of an object is constant, its kinetic energy depends only on velocity. It means if the velocity is more, it will have maximum kinetic energy. For the interval of 31-40 m/s, the kinetic energy of the object is maximum.
Answer:
The alligator will take t = 10 s to reach the final speed of 35 m/s
Explanation:
As we know that the initial speed of the alligator is 5 m/s
then it accelerate by given acceleration to reach the final speed of 35 m/s
so we will have
now we have
Answer:
300 clicks...
Explanation:
Output on 3 clicks = 10 dB
Increasing 10 by a factor of 100 equals 1000 dB so,
Its simple math, clicks will also increase in the same ratio and it shall take 300 clicks to increase the volume by a factor of 100.
Answer:
2.41m/s
Explanation:
Given parameters:
Initial velocity = 1.5m/s
Acceleration = 0.275m/s²
Distance = 6.45m
Unknown:
Final velocity = ?
Solution:
To solve this problem, we apply the kinematics equation below:
v² = u² + 2aS
v is the final velocity
u is the initial velocity
a is the acceleration
S is the distance
v² = 1.5² + (2 x 0.275 x 6.45)
v = 2.41m/s
