A projectile is fired horizontally with speed v0 from the top of a cliff of height h. Itimmediately enters a fixed tube with length x, as shown in Figure. There is friction between the projectileand the tube, the effect of which is to make the projectile decelerate with constant acceleration ax. After theprojectile leaves the tube, it undergoes normal projectile motion down to the ground. Calculate the totalhorizontal distance, l, that the projectile travels. (g=9.8 m/s2) v0=5.5m/s ax=-2.5m/s2 x=4.5m h=12m
In the blizzard of ’88, a rancher was forced to drop hay bales from an airplane to feed her cattle. The plane flew horizontally at 160 km/hr and dropped the bales from a height of 80 m above the flat range, (a) She wanted the bales of hay to land 30 m behind the cattle so as to not hit them. Where should she push the bales out of the airplane? (b) To not hit the cattle, what is the largest time error she could make while pushing the bales out of the airplane? Ignore air resistance.
A ball is thrown vertically upward with an initial speed of 9.0 m/s then falls back to its initial position. If you are to ignore the air resistance, what will be the total displacement of the ball?
Cite an instance in which your speed could be zero while your acceleration is nonzero.
An elevator is traveling downward at decreasing speed. If up as chosen as the positive direction, then the acceleration of the elevator is _____. A. negative B. positive C. zero D. not enough information to determine
Consider an airplane whose takeoff speed is 220 km/h and that takes 15 s to take off at sea level. For an airport at an elevation of 1600 m (such as Denver), determine (a) the takeoff speed, (b) the takeoff time, and (c) the additional runway length required for this airplane. Assume constant acceleration for both cases.
A ball is thrown from the ground with an initial velocity of 20 m/s at an angle of 30 degrees above the horizontal. Ignoring air resistance, calculate the maximum height reached by the ball and the horizontal distance it travels before hitting the ground. Assume the acceleration due to gravity, g, is 9.8 m/s² and take the direction of upward motion as positive.
As soon as a ball was allowed to fall from rest from height h, a second ball was thrown upwards from the ground in the vertical direction. For two balls to meet at height h / 2, what should the initial velocity of the second ball be?
Does the initial velocity of an object have anything to do with its acceleration? For example, compared to dropping an object, if you throw it downward would the acceleration be different after you released it?
Now, imagine an elephant and a feather under free-fall (if there is no air resistance) being dropped from the same height at the same exact moment. Which one do you think will reach the ground first? How can you tell?
A ball is thrown upward from the ground, with a certain initial speed. The ball goes up and lands back on the ground. Which value (s) (v0, y, v, a, t ,...) is (are) zero ?
The record distance in the sport of throwing cowpats is 81.1 m. This record toss was set by Steve Urner of the United States in 1981. Assuming the initial launch angle was 45° and neglecting air resistance, determine the following: (a) the initial speed of the projectile and (b) the total time the projectile was in flight.
