I need help with these practice test problems. I also need to see work cause I...
A daredevil is shot out of a cannon at 45.0° to the horizontal with an initial speed of 30.5 m/s. A net is positioned a horizontal distance of 52.5 m from the cannon. At what height above the cannon should the net be placed in order to catch the daredevil?
A daredevil is shot out of a cannon at 45.0° to the horizontal with an initial speed of 28.0 m/s. A net is positioned a horizontal distance of 51.0 m from the cannon. At what height above the cannon should the net be placed in order to catch the daredevil?
Can someone please work these step-by-step. I have the answers but needing to know how to work them. 5. A hammer is dropped from the top of a tower that is 400 m high. If we neglect air resistance so that the only force on the hammer is gravity, with what velocity does the hammer strike the ground? 6. A cowboy shoots a bullet straight up into the air with an initial speed of 800 m/s. If the bullet is...
Hi I need help with the following problems: 1.A ball is thrown horizontally from the roof of a building 45.0 m tall and lands 24.0 m from the base. What was the ball’s initial speed? 2.A football is kicked at ground level with a speed of at an angle of 36.9º to the horizontal. How much later does it hit the ground? How height does it rise? What is its range? 3.A projectile is fired with an initial speed of...
please help am doubting my analysis i. Solve the following problem on a clean sheet of paper. A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m. The cannonball is launched with an initial velocity of 110 m/s at an angle of 64° above the horizontal. Neglect air resistance. Assume the cannonball hits the cliff as it descends (on its way down) exactly at the edge,...
I need some confirmation with a, b, and c. I think I have it but am definitely second guessing. Thank you! 14. A cannonball shot from a buried cannon is fired at an angle of 370 above a level field. The initial velocity has a magnitude 50 m/s. , 50 m/s 370 Neglect air resistance and answer the following questions: a) Find the horizontal and vertical components of the vector v b) How many seconds does the cannonball stay in...
The answers to these physics problems are from my textbook. I need help with getting to the answer. 1) an automobile manufacturer claims that its product will, starting from rest, travel 0.40 km in 9.00s. What is the magnitude of the constant acceleration required to do this? answer: 9.9 m/s^2 2) A stone is thrown from the top of a building with an initial velocity of 20 m/s downward. The top of the building is 60 m above the ground....
A circus act consists of a performer (a "human cannonball") being launched from a cannon into a net at the other end of the stage. The performer (mass 60 kg) leaves the cannon at a speed of 25 m/s at an angle of 30o above horizontal. She comes out of the cannon at a height of 2 meters above the ground and lands in the net at a horizontal distance of 45 meters away from the launch point. 1. How...
Answer all please In all problems, neglect air drag and use g- 10 m/s2 when needed. 1. A car initially moving at 30 m/s in a straight direction, reduces its speed to 10 m/s in a time of 10 seconds. Calculate the distance travelled by the car. 2. A cannon positioned on a flat, horizontal ground shoots a shell with muzzle speed of 180 m/s. Calculate the maximum height reached by the shell if (i) It is shot in a...
A daredevil on a motorcycle leaves the speed of a ramp with a speed of 33.5 m/s as in the figure below. If his speed is 31.8 m/s when he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance, m A 44.0-kg projectile is fired at an angle of 30.0 degree above the horizontal with an initial speed of 1 40 times 102 m/s from the top of a cliff...
