Compressed air is used to fire a 60 g ball vertically upward from a 0.70-m-tall tube. The air exerts an upward force of 2.4 N on the ball as long as it is in the tube. Part A How high does the ball go above the top of the tube? Express your answer to two significant figures and include the appropriate units
A ball is thrown vertically upward with a velocity of 15 m/s from the roof of building that is 22 m high. How long does it take to hit the ground below? How fast was it going when it hit?
A ball falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m. Assume that mall 0.390 kg. (a) What is the impulse (in kg. m/s) delivered to the ball by the floor? (b) If the ball is in contact with the floor for 0.0400 seconds, what is the average force (in N) the floor exerts on the ball?
A 400 g steel block rotates on a steel table while attached to a 1.20 m -long hollow tube. Compressed air fed through the tube and ejected from a nozzle on the back of the block exerts a thrust force of 5.21 NN perpendicular to the tube. The maximum tension the tube can withstand without breaking is 40.0 N . Assume the coefficient of kinetic friction between steel block and steel table is 0.60.
A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...
A ball A is thrown vertically upward from the top of a 33-m-high building with an initial velocity of 3 m/s. At the same instant another ball B is thrown upward from the ground with an initial velocity of 23 m/s. Determine the height from the ground at which they pass. Determine the time at which they pass.
A ball is thrown vertically upward with a speed of 25.0 m/s.(a) How high does it rise? (b) How long does it take to reachits highest point? (c) How long does the ball take to hit theground after it reaches its highest point? (d) What is itsvelocity when it returns to the level from which it started?
A small rubber ball is launched by a compressed-air cannon from ground level with an initial speed of 13.5 m/s directly upward. Choose upward as the positive direction in your analysis. (a) What is the maximum height above the ground that the ball reaches? m (b) How long does it take to reach the maximum height? s (c) How long does it take to reach the ground after it reaches its highest point? s (d) What is its velocity just...
If a ball is thrown upward from a building 30 m tall and the ball has a vertical velocity of 25 m/s, then its approximate height above the ground t seconds later is given by h(t) = 30 + 25t - 5t^2 a. After how many seconds does the ball hit the ground? b. What is the domain of h? c. How high does the ball go?
A basketball is thrown vertically upward with an initial velocity of 22.8 m/s. 'a) How long (s) does the ball take to reach its maximum height? 'b) How high (km) does the basketball go?
