3. A projectile is fired up an incline (incline angle º) with an initial speed v, at an angle 0, with respect to the horizontal (0> 0) as shown in ??. (a) Show that the projectile travels a distance d up the incline, where 2 v cos e sin(0- ) d= g cos 0 (b) For what value of 0; is d a maximum, and what is that maximum value? Path of the projectile ya d 16 Figure 2: ASIWO3​

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
