Answer:
1.0s
Explanation:
distance = 1/2 × acceleration × time2 + intial speed × time
Answer:
Real and inverted
Explanation:
Magnification of a lens is defined as the ratio of the height of the image to the height of the object.
Where
h' is the height of image
h is the height of the object
It is also defined as the ratio of image distance to the object distance.
Here, m = -0.6
Negative sign shows the image is inverted. So, the formed image will be real and inverted.

hope this help
3.5 Newton of force is needed to accelerate 140g of ball at 25 m/s^2 using the formula f=ma
Change 140g to kg
Answer:
y = 0m
y0 = 166m
v0y = 0 m/s
g = 9.8 m/s^2
t = ?
Solve for t:
y = y0 + v0y*t - (0.5)gt^2
0 = 166 - (0.5)(9.8)t^2
t = 5.82 s
Now, using time, we can solve for the range using the equation:
x = vx(t)
x = (40)(5.82)
x = 232.8 m
The impact horizontal component of velocity will be 40 m/s as velocity in terms of x is always constant. To find the impact vertical component of velocity, we use the equation:
v = v0y - gt
v = 0 - (9.8)(5.82)
v = -57.04 m/s
