ional problems (1). A bullet is fired horizontally with initial velocity of 800 m/s as a target located 200 m from the rifle. (a). How much time is required for the bullet to reach the target? (b). How far does the bullet fall in this time (g = 9.81 m/s2)

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
