Hello there!

Greetings!

The escape velocity is not dependent on the angle of projection so even though the angle of projection is 45 degree now , escape velocity will remain unchanged,  it will be still 11.2 km per second.

Thankyou

Hello yashwanth!! escape velocity is independent on the direction of propagation.so it remains same and the answer is 11.2km/s
