2. A baseball is thrown straight up with an initial speed of 14.7 m/s from the roof of a building Hp 111.5 m high. (Use the coordinate system shown at the right. Assume the baseball is thrown upward from the edge of the roof, so that it can travel back down to the ground without colliding with the roof. Ignore air resistance. Be sure to include the correct sign and units with any numerical answer. Use g...

You are experimenting with a cart on a track that can launch a ball straight up into the air. (1) Suppose the cart is moving at 2.0 m/s along the horizontal track and the ball is launched to a height of 1.0 m above the level of the cart. How far away will the cart catch the ball? (2) Now you tilt the track to 10° and let the cart go from rest at the moment the ball is launched....

A sociologist claims that children spent more time watching television in 1981 than children do today. A study was conducted in 1981 to find the time that children watched television on weekdays. Recently, a similar study was conducted. The results of these studies (in hours per weekday are shown below. Assume the population standard deviation is 0.7 for 1981 and 0.8 for today, At a = 0.05, can you support the sociologist's claim? Complete parts (a) through (d) below. Full...
