Answer:
3.2 seconds
Explanation:
When the cars collide, they have the same position.
x₁ = x₂
-4 + 1.1t = 8.8 − 2.9t
4t = 12.8
t = 3.2
Project a electron beam. if it changes its path, then there is a possibility of presence of magnetic field
A is a good example, i suppose.
Acceleration of the ball is ![50 m/s^2](https://tex.z-dn.net/?f=50%20m%2Fs%5E2)
Explanation:
The acceleration of the ball can be found by using Newton's second law of motion, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:
![F=ma](https://tex.z-dn.net/?f=F%3Dma)
where
F is the net force
m is the mass
a is the acceleration
For the ball in this problem, we have
m = 0.50 kg (mass)
F = 25 N (force)
thereofre, the acceleration of the ball is
![a=\frac{F}{m}=\frac{25}{0.50}=50 m/s^2](https://tex.z-dn.net/?f=a%3D%5Cfrac%7BF%7D%7Bm%7D%3D%5Cfrac%7B25%7D%7B0.50%7D%3D50%20m%2Fs%5E2)
