Answer:
1.944m_s²
Explanation:
First convert speed from km/h to m/s the use the formula a=v-u
t
Answer:
12.5 J
Explanation:
Force, F = 25 N
Distance, d = 0.5 m
The direction of force and the displacement is same.
Work is defined as the product of force in the direction of displacement and the displacement.
Work = Force x displacement x CosФ
Where, Ф be the angle between force and the displacement
Here, Ф = 0°
So, W = 25 x 0.5 x Cos0°
W = 12.5 J
We Know: MA = d₁ / d₂
Here, d₁ = 4
d₂ = 10-4 = 6
Substitute their values into the expression:
MA = 4/6
MA = 2/3
So, Your Answer would be 2/3
Hope this helps!
