While we're at it I need help with part c and d too

The Hubble Space Telescope (HST), launched in 1990, will someday be
decommissioned. It will fire its retrorockets, fall back into Earth's atmosphere
and crash harmlessly into the Pacific Ocean. Let us study the dynamics of this
operation. Assume that the HST is currently in a circular orbit around the
Earth and that the retrorockets will fire in precisely the opposite direction of
its motion. The HST has an orbital period of 95.6 minutes.
a) What is the radius of the HST's orbit? [2m]
b) What is the orbital velocity of the HST? [2m]
c) What is the minimum ΔV required to crash the HST into the Earth's
surface? [4m]
Briefly explain why such a trajectory would be unwise. [1m]
d) NASA suggests that the HST should impact the ocean at an angle of at
most 75° from the vertical. What would be the ΔV required to
accomplish this? Neglect air resistance. [5m]

Credit Singapore Astronomy Olympiad 2017 to ensure i wont get sued.

I know c), i might try to do d) when i get some idea, for now nah.

(Since you know a and b, i skipped calculating orbital velocity and radius of orbit... also i was bored to calculate this...)
