A projectile fired from a gun has initial horizontal and vertical components of velocity equal to 30 m/s and 40 m/s, respectively. a. determine the initial speed of the projectile b. at what angle is the projectile fired (measured with respect to the horizontal)? c. approximately how long does it take the projectile to reach the highest point in its trajectory?
A rocket can be fired with a velocity of 32m/s. At what angle above the horizontal, must it be fired so that it clears a 9.33m barrier at its highest point?
You toss a ball into the air at an initial angle of 40∘40∘ above the horizontal. At what point in the ball’s trajectory does the ball have the smallest speed? (Neglect any effects due to air resistance). at the highest point in its flight just after it is tossed just before it hits the ground halfway between the ground and the highest point on the fall portion of the trajectory halfway between the ground and the highest point on the...
A 2 kg rock is fired at an angle of 60 degree above the horizontal with an initial speed 20 m/s by someone standing on the edge of a cliff 40 m above level ground. The initial position of the rock is taken to be y = 0. Air resistance is not neglected in this situation! (a) The initial mechanical energy of the rock is? (b) The work being done on the rock by the force of gravity after being...
A bullet is fired from ground level with a speed of 150 m/s at an angle 30.0° above the horizontal at a location where g = 10.0 m/s2. What is the horizontal component of its velocity when it is at the highest point of its trajectory?
