You need to calibrate your giant paint ball bazooka, so you fire it at an angle of 60° and you find that the giant paint ball splatters the ground at a horizontal distance of 107 m from the end of the muzzle, and a distance of 1.7 m below the end of the muzzle. What is the muzzle velocity, vo, of your giant paint ball bazooka,
b. how long does it take for the giant paint ball to hit the ground and splatter,
c. what is the y-component of its velocity just before it splatters,
d. and what is its velocity ... magnitude and
e. direction, just before it splatters.

An automobile of mass 2000 kg moving at 30 m/s is braked suddenly with a constant braking force of 10000 n. how far does the car travel before stopping?

Consider two metallic rods mounted on insulated supports. one is neutral, the other positively charged. you bring the two rods close to each, but without contact, and briefly ground the the neutral rod by touching it with your hand. show answer correct answer what would be resulting charge (if any) on the initially neutral rod

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
