Assuming constant acceleration <em>a</em>, the object has undergoes an acceleration of
<em>a</em> = (50 m/s - 100 m/s) / (25 s) = -2 m/s²
Then the net force has a magnitude <em>F</em> such that, by Newton's second law,
<em>F</em> = (75.0 kg) <em>a</em>
<em>F</em> = (75.0 kg) (-2 m/s²)
<em>F</em> = -150 N
meaning the object is acted upon by a net force of 150 N in the direction opposite the initial direction in which the object is moving.
Answer:
push up agaisnt you with equal force.
Answer:
option (D)
Explanation:
your distance from the plane mirror = 2.4 m
According to the property of the plane mirror, the distance between the object and the mirror is equal to the distance between the image and the mirror.
So, the distance between you and your image is two times the distance between you and mirror.
the distance between you and your image = 2 x 2.4 = 4.8 m
westerlies
polar easterlies and trade winds are in a different type
Finding out the acceleration 12/3 = 4m/s^2
thus it is descending so the actual acceleration would be 9.8-4 = 5.8 m/s^2
the weight will be 90*5.8 = 522 N
522/9.8 = 53.2 kg
