Question 7 A projectile fired from a gun has initial horizontal and vertical components of velocity equal to 280 m/s and 370 m/s, respectively. Determine the maximum height above the gun that the projectile reaches in its trajectory. 19 m 38 m 7000 m 3500 m 8.You want to throw a water balloon horizontally from the top of a 10 m building and hit a baby sitting 10 m from the base of the building. What should the initial speed be? 1.4 m/s 7 m/s 9 m/s 5 m/s 12.  The coefficient of kinetic friction between the tires of a car and a wet road surface is 0.52. If the car is traveling at an initial speed of 25 m/s, and then slams on the breaks so the car skids straight ahead to a stop, how far does the car skid?  Assume the mass of the car to be 1000 kg. 57 m 61 m 123 m 32 m

A projectile is launched from point A with speed Vo = 22 m/s. Determine the value of the launch angle a which maximizes the range R indicated in the figure. Determine the corresponding value R. 22 m/s A 22.3 m 35 m R-

Two projectiles are launched from the same point at the same angle, but the first one has twice the initial velocity compared to the second. The ranges R1 and R2 are: O A. R2 = 4R1 O B. R1 = 4R2 OC R2= 2R1 OD R1 = R2 O E None of the above.
