- A person launches a rock with an initial speed of 300 m/s at an angle of 45 degrees above the horizontal. What is the speed of the rock when it reaches its maximum height? Give your answer to 2 significant figures.A batter hits a fly ball with an initial velocity of 37 m/s at an angle of 32° from the horizontal. How much time does the outfielder have to get to the appropriate position to catch the ball?James throws a ball at an initial velocity of 8.4 m/s at an angle of 7.9 above the horizontal. What is the maximum height?
- Two people each kick identical balls at the same angle. Person A kicks it at three times the speed of person B. How many times higher does A's ball go than B's?A blue person throws an object with an initial velocity of 25.0 m/s at an angle of 37.0°. A green person stands 15.0 meters in front of the blue person and throws an object straight up. Assume that both objects are thrown from the same initial elevation. If both people throw their objects at the same time, with what initial speedmust the green person throw their object such that theycollide? Answers: ~15.0 m/sA projectile is to be launched at an angle of 30° so that it falls beyond the pond of length 20 meters as shown in the figure. a) What is the range of values of the initial velocity so that the projectile falls between points M and N? Vo 30° M 10m 10 m 20 m
- A circus cat has been trained to leap off a 12-m-high platform and land on a pillow. The cat leaps off at vo = 3.1 m/s and an angle = 22° (see figure below). (a) Where should the trainer place the pillow so that the cat lands safely? d = X Your response differs from the correct answer by more than 100%. m (b) What is the cat's velocity as she lands in the pillow? (Express your answer in vector form.) Vf= m/sThe horizontal and vertical components of the initial velocity of a football are 24 m/s and 7 m/s respectively. What is the initial velocity of the football?During the siege of Constantinople that led to its conquest by the Ottomans in 1453, the Hungarian engineer Orban built a set of bombards (primitive cannon) to throw enormous stones at the city to breach its walls. The largest of these could throw a 300 kg stone a distance x = 2 km. Assume that the stone was launched at an angle of 0 = 45 degrees above the horizontal; in the absence of air resistance, this gives the largest range. a) What speed did the stone have to be launched at to achieve this range? b) How long was the ball in the air? c) How fast was the ball traveling at the apex of its flight?
