Alpha Centauri A is about 93 million miles away from the Earth and it takes light 4.367 years to reach there.
Answer:
d = 18 m
Explanation:
Given that,
The speed of a baseball, v = 36 m/s
We need to find the distance from the mound to home plate if the ball takes 0.5 seconds to leave the pitcher's hand and cross the plate.
Let the distance be d. We can find it using the formula,
Speed = distance/time
or
So, the required distance is equal to 18 m.
Answer:
Impulse = 4Ns
Explanation:
Given the following data;
Force = 2N
Time = 2 seconds
To find the impulse experienced by the object;
Impulse = force * time
Impulse = 2*2
Impulse = 4Ns
Therefore, the impulse experienced by the object is 4 Newton-seconds.
Padded dashboards make automobiles safer because it will increase the time required to stop your head from moving forward during an accident. The increased stopping time results in a smaller force being applied to the person's head.
