Then the tangent of angle-Θ is (Ay / Ax).
Answer:
<h2>441 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
PE = 30 × 9.8 × 1.5
We have the final answer as
<h3>441 J</h3>

By conservation of momentum,
Distance lighter fragment slide= 7*6.7=46.9m
120 km/3 hours. 40/1=?/3 1x3=3 hours so 40x3=120 km
