- A gun is on the same horizontal level as a target 484 meters away. A bullet is fired from the gun with a muzzle velocity of 154m/s. At what angle of elecation should the muzzle of the gun be set in order to ensure the bullet hits the target? Hint: You may use the formulas for the horixzontal x(t) and vertical y(t) displacement of the particle: x(t) = ucos(α)t, y(t) - usin(α)t - ½gt2 , g = 10m/sec2.A solid 1-m-diameter sphere fl oats at the interface betweenwater (SG = 1.0) and mercury (SG = 13.56) such that 40percent is in the water. What is the specifi c gravity of thesphere?( a ) 6.02, ( b ) 7.28, ( c ) 7.78, ( d ) 8.54, ( e ) 12.56By using the expression for the shear stress derived in class (and in BSL), show that the shear force on asphere spinning at a constant angular velocity in a Stokes’ flow, is zero.This means that a neutrally buoyant sphere (weight equal buoyancy force) that is made to spin in aStokes’ flow, will neither rise nor fall, nor translate in any preferential direction in the (x-y) plane. expressions for velocity are: v_r (r,θ)= U_∞ [1-3R/2r+R^3/(2r^3 )] cosθ v_θ (r,θ)= -U_∞ [1-3R/4r-R^3/(4r^3 )] sinθ Where v_r and v_θ are the radial and angle velocity, U_∞ is the velocity of fluid coming to sphere which very faar away from the sphere. And R is the radius of sphere.
