Answer:
kinetic energy at first
Explanation:
kinetic turns to potential as it gains height
Answer:
sweeps out equal areas in equal times.
Explanation:
As we know that there is no torque due to Sun on the planets revolving about the sun
so we will have
now we have
now we also know that
so rate of change in area is given as
so we will have
since angular momentum and mass is constant here so
all planets sweeps out equal areas in equal times.
Use the impulse-momentum theorem.
Substitute your known values:
