Question

Can anybody help mesolve this problem:
A shell is fired from the ground with an initial speed of 1.70x10to the third power m/s
( approximately five times the speed of sound)
at an initial angle of 55.0 degrees to the horizontal. Neglectingair resistance, find
a) shell's horizontal range
b)the amt. of time the shell is in motion Please Explain the solving step by step, includingformulas. Thank You in Advance (; Can anybody help mesolve this problem:

Explanation / Answer

v = 1.7*10^3 = 55 y = vsint + 0.5at^2 0 = (1.7*10^3)sin55t + (0.5) (-9.8)t ^2 0 =1392.558t - 4.9t^2 1392.558t = 4.9t^2 4.9t = 1392.558 t = 2.539 seconds x = vcost + 0.5at^2 x = (1.7*10^3)cos55(2.539) + 0 x = 2475.728 m Hopefully this helps!
