Shot a bullet vertically up in the air and measured how much time it took to fall to the ground. They measured the time of flight to be 1 minute 50 seconds. The air resistance significantly affects the motion (especially at high velocities) but for the sake of calculations, lets ignore this effect for now. 1) How high did the bullet reach? 2) Can you calculate the initial velocity of the bullet? 3)The bullet was just falling from the sky....

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...

8. A rocket is launched vertically upwards and experiences an acceleration of 4x10 m.s2 for 8 seconds. After this time, the engine is turned off and the rocket continues to rise to its maximum height. (a) Explain (using Newton's third law) why the rocket moves forward during the first 8 seconds. (2) (b) Calculate the velocity of the rocket 8 seconds after launching (2) (c) How long after launching does the rocket reach its maximum height? (2) (d) (2) At...

In order to defeat Bowser, suppose Mario launched a stone from his sling with an initial velocity of 30.5 m/s at an angle θ=20 degrees above the horizontal. The stone flies through the air and strikes Bowser between the eyes exactly 2.00 seconds after it was released. Assume Mario and Bowser are standing on flat ground, and the stone strikes Bowser on its way back down (after reaching its maximum height). You may neglect air resistance. A) how far away...
