Answer:
160m/s
Explanation:
The Ferrari is moving by uniformly accelerated motion, with constant acceleration of a = 50 m/s^2, and initial velocity u = 10 m/s. The velocity at time t of the car is given by
v(t)=u+at
where
u = 10 m/s
a = 50 m/s^2
If we substitute t = 3 s into the equation, we can find the velocity of the car after 3 seconds:
v(3s) = 10m/s + (50m/s^2)(3s)=160m/s
Burning, in general, is a chemical change.
Why?
This is because we are breaking and/or forming new bonds. We form a totally different substance.
Answer:
300N
Explanation:
If both people push the box in the same direction the force applied to the box is the sum of the N from both peoplef:
100N + 200N = 300N
0.09 / 6.37 x 10⁶ = 1.4129 x 10⁻⁸
The radius of the baseball is 1.4129 x 10⁻⁸ the radius of the Earth.
