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,...

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...
