Newton's 2nd law of motion:
Force = (mass) x (acceleration)
= (1,750 kg) x (1.35 m/s²)
= 2,362.5 Newtons
(about 531 pounds)
Answer:
Please see below as the answer is self- explanatory.
Explanation:
- Any time that an object changes direction (from leftward to rightwward, or from upward to downward) the velocity must be zero just for one instant, when is on the verge of changing the direction.
- This is needed because velocity changes as a continuous function of time, so it needs to cross the t-axis when passing from positive to negative or vice versa.
- However, the claim that in the moment that velocity is zero, the acceleration is also zero, is false.
- Due to acceleration is the rate of change of velocity, and velocity is a vector, this means at any time there is a change of direction, there is an acceleration that is non-zero.
- For example, when an object that has been thrown upward, reaches to its maximum height, just one instant before starting to fall, the velocity becomes zero, but the acceleration (which causes the object to fall) is non-zero, due to it's the acceleration due to gravity.
The big bang is a theory of our universe and many others along with making our solar system. Meanwhile, in other universes have are solar system as well that is why we see stars at night because the sun and it's rays are so bright during the day it blocks them out.
Explanation:
B. leads to muscle strain.
30N
Explanation:
Given parameters:
Mass of object = 15kg
Acceleration = 2m/s
Unknown:
Force = ?
Solution:
Force is given as the product of mass and acceleration:
F = m x a
m is the mass
a is the acceleration
Inputting the parameters:
F = 15 x 2 = 30N
The unit of force is newtons, N .
