A ball is dropped from the top of a building 100 m high. (Ignore air resistance) a) How long does it take the ball to hit the ground? b) What is the speed of the ball when it hits the ground?
A ball is dropped from a building 110m high and hits the ground. What was its final velocity in m/s just as it hit the ground
A stone thrown horizontally from a height of 6.27 m hits the ground at a distance of 12.10 m. Calculate the initial speed of the stone. Neglect air resistance. Submit Answer Tries 0/99 Calculate the speed of the stone as it hits the ground. Neglect air resistance.
1) Shayla is sliding in a sled from a top of a 5-m-high snow hill ( starting from rest.) At the bottom of the hill, her sled hits Tom, who falls into the sled. Toms's mass is the same as Shayla's and her sled altogether. What is the speed of the sled after Tom fell in? Neglect friction w/ snow. 2) You are standing by a smooth frozen lake, and longing to propel a snowball over the lake. In which...
help! Three objects are dropped from the top of a building. The first is thrown straight down with a velocity v, the second is thrown straight up with a velocity 2v, and the third is simply dropped. Which one f highest speed when it hits the ground? (Ignore air resistance.) The first. The third. They all have the same velocity. The second.
A 55.0 kg skier with an initial speed of 11.0 m/s coasts up a 2.50 m high rise as shown in the following figure. Vi = ? KE 2.5 m / 35° Find her final speed at the top (in m/s), given that the coefficient of friction between her skis and the snow is 0.0800. (Hint: Find the distance traveled up the incline assuming a straight-line path as shown in the figure.) m/s
A brick is dropped (zero initial speed) from the roof of a building. The brick strikes the ground in 2.10 s. You may ignore air resistance, so the brick is in free fall. a) How tall, in meters, is the building? (b) What is the magnitude of the brick's velocity just before it reaches the ground? m/s (e) Sketch ay t, vy t, and yt graphs for the motion of the brick. (Do this on paper, Your instructor may ask...
A 55.0 kg skier with an initial speed of 14.0 m/s coasts up a 2.50 m high rise as shown in Figure 6.23. Find his final speed at the top, given that the coefficient of friction between her skis and the snow is 0.0800. (Hint: Find the distance traveled up the incline assuming a straight-line path as shown in the figure.)
A 3.00 kg ball is dropped from the roof of a building 176.4 m high. While the ball is falling to Earth, a horizontal wind exerts a constant force of 12.0 N on it. a.)How far from the building does the ball hit the ground? b.)How long does it take to hit the ground? c.)What is its speed when it hits the ground?
A 5.00-kg watermelon is dropped from rest from the roof of a 20.0-m -tall building and feels no appreciable air resistance. Part A) Calculate the work done by gravity on the watermelon during its displacement from the roof to the ground. Part B) Just before it strikes the ground, what is the watermelon's kinetic energy? Part C) Just before it strikes the ground, what is the watermelon's speed? Part D) Would the answer in part A be different if there...
