Question 7 A projectile fired from a gun has initial horizontal and vertical components of velocity equal to 280 m/s and 370 m/s, respectively. Determine the maximum height above the gun that the projectile reaches in its trajectory. 19 m 38 m 7000 m 3500 m 8.You want to throw a water balloon horizontally from the top of a 10 m building and hit a baby sitting 10 m from the base of the building. What should the initial speed be? 1.4 m/s 7 m/s 9 m/s 5 m/s 12. The coefficient of kinetic friction between the tires of a car and a wet road surface is 0.52. If the car is traveling at an initial speed of 25 m/s, and then slams on the breaks so the car skids straight ahead to a stop, how far does the car skid? Assume the mass of the car to be 1000 kg. 57 m 61 m 123 m 32 m
24. A shell is fired with a horizontal velocity in the positive x direction at a speed of 330 m/s from the top of an 80- m high cliff. The shell strikes the ground 1330 m from the base of the cliff. What is the magnitude of the velocity of the shell as it hits the ground? Hint: you need to determine horizontal and vertical components of the final velocity first, from the kinematic equations, then calculate magnitude of the velocity. While the horizontal velocity remains constant, the vertical velocity does not. You will need time of flight to determine the latter. 80 m 1330 m A) 4.0 m/s B) 9.8 m/s B) 9.8 m/s C) 82 m/s D) 170 m/s (E) 332 m/s
You throw a ball up at some angle above the horizontal so that its velocity is (v0x, v0y). You then run 22.0 m forward on level ground and catch the ball 2.90 s later at the same altitude it was released from. a) How high above the release point did the ball reach? b) What was the horizontal component of the ball’s initial velocity, v0x? c) What was the vertical component of the ball’s initial velocity, v0y?

Several people stand on a bridge over a river. The bridge is not level, so the people are all different heights above the river. Each person throws a stone to the river. a) The first person is 26.8 m above the river and throws her stone with a speed of 16.6 m/s at an angle of 6 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below). How long does it take her stone to hit the water, in seconds? b) The second person is 19.0 m above the river and throws his stone with a speed of 17.1 m/s at an angle of -21.4 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below). What is the range of his stone, in meters? c)The third person is 9.1 m above the river and throws their stone with a speed of 6.5 m/s at an angle of 9.3 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below). What is the speed of this stone (in m/s) just before it strikes the river?
Answer this question
A person standing 20.0 meters away from a wall throws a stone from the ground level at an angle of 60.0°above the horizontal with an initial speed of 25.0 m/s. The time it takes the stone to reach the wall and the height at which the stone strikes the wall are: a.) t = 1.4 s, y = 18.6 m b.) t=2.6s, y=11.5m c.) t = 1.6 s, y = 22.1 m d.) t=6.8s, y=34.2m
