When acceleration is zero (that is, a = dv/dt = 0), rate of change of velocity is zero. That is, acceleration is zero when the velocity of the object is constant. so probably D
Explanation:
D
1) 2 kilograms converted into grams is 2000
2) 5200 meters converted into kilometers is 5.2
3) 20 centimeters converted into meters is 0.2
Answer :
The distance is 109.89 m.
Explanation :
Given that,
Height = 40 m
Angle = 20°
We need to calculate the base of the plateau
Using formula of angle

Where, h = height
x = base
= angle
Put the value into the formula



Hence, The distance is 109.89 m.
