- Neglecting air resistance, how long would it take an object to fall to Earth from a height of 234m?For the horizontal projectile shot from a height of 10.0 m above the ground with a speed of 15.0 m/s. Calculate the time (in seconds) the projectile in the air: (use 3 decimal places)At a long distance shooting match, a bullet is fired with a muzzle velocity of 3000 feet per second from a rifle held in the horizontal position. When fired the sights of the rifle was dead center of a target. The bullet strikes the target at 4.00 ft below the center of the target. How long (in seconds) did it take for the bullet to reach the target? How far away (in unit of yards) was the target? Neglect any air resistance to the bullet. Make a simple sketch. Make a list of all given values, units, and the variables they represent. write the general form of the equation you are going to use. Insert the known values and solve. For problems with vertical motion State at the start of the problem which direction is positive by using an up or down arrow. Keep the velocity components and time to 2 decimal places
- A ball is thrown upward at an angle of 300 to the horizontal and lands on the top ofthe edge of a building that is 20 m away. The top edge is 5 m above the throwingpoint. How fast was the ball thrown?A ball is shot with a velocity of 36 m/s at an angle of 67o from the top of a 23 m tall building. What is the horizontal distance the ball travels when it hits the ground?A mountain climber stands at the top of a 35.0 m cliff that overhangs a calm pool of water. She throws two stones vertically downward 1.00 s apart and observes that they cause a single splash. The first stone had an initial velocity of -1.20 m/s. (a) How long after release of the first stone did the two stones hit the water? (Round your answer to at least two decimal places.) 7.14 Your response differs from the correct answer by more than 100%. s (b) What initial velocity must the second stone have had, given that they hit the water simultaneously? -33.7 Your response differs from the correct answer by more than 100%. m/s (c) What was the velocity of each stone at the instant it hit the water? first stone -26.16 m/s -26.16 second stone Your response differs from the correct answer by more than 10%. Double check your calculations. m/s
