Question

A shell is fired from the ground with an initial speed of 1.70 × 103 m/s (approximately five times the speed of sound) at an initial angle of 40.0◦ to the horizontal.
The acceleration of gravity is 9.81 m/s2 .
a) Neglecting air resistance, find the shell’s horizontal range.
Answer in units of m.

Answer 1

The shell’s horizontal range

R=(v_0^2 sin⁡2θ)/g

=((1.70×〖10〗^3 )^2 sin⁡〖(2×40.0°)〗)/9.81=290000 m
