no te tengo porque darte explicaciones
Answer:a)45cos40 b)45sin40 c) 2.95 d)102
Explanation:
a) ![v_{x} = 45 cos40](https://tex.z-dn.net/?f=v_%7Bx%7D%20%3D%2045%20cos40)
b) ![v_{y}=45sin40](https://tex.z-dn.net/?f=v_%7By%7D%3D45sin40)
c) Since air resistance is negligible, the only force acting on the golf ball is gravity. Thus, its vertical acceleration is -<em>g</em>. We know the final velocity must be 0 m/s, because this will be when the golf ball reaches the maximum height and starts to change direction (it falls back to the ground). We also know initial velocity in the vertical direction (see part b). Thus, we can use this equation:
.
![0 m/s = 45sin40 + (-9.8m/s^2)t\\t = 2.95s](https://tex.z-dn.net/?f=0%20m%2Fs%20%3D%2045sin40%20%2B%20%28-9.8m%2Fs%5E2%29t%5C%5Ct%20%3D%202.95s)
d) The horizontal distance traveled is dependent on (1) how long the ball is in the air and (2) what the horizontal velocity is. (1) was found in part c, and (2) was found in part a.
![x=vt\\x=45cos40(2.95) =102m](https://tex.z-dn.net/?f=x%3Dvt%5C%5Cx%3D45cos40%282.95%29%20%3D102m)
answer
6000 N
explanation
every force has an equal and opposite reaction force, so the force exerted by the truck on the car is the same as the force exerted by the car on truck
the force is 6000 N
