A bullet is shot straight up into the air. Its initial speed is 7.5 km/s. What height will it reach? Assume air resistance is absent.
A bullet is shot through two cardboard disks attached a distance D apart to a shaft turning with a rotational period T, as shown.
A bullet is shot through two cardboard disks attached a distance D apart to a shaft turning with a rotational period T, as shown. Derive a formula for the bullet speed u in terms of D, T, and a measured angle e between the position of the hole in the first disk and that of the hole in the second. If required, use r, not its numeric equivalent. Both of the holes lie at the same radial distance from the shaft....

iPad 3:59 PM * 48%. 115:33:08 Exit 1 A rifle is fired straight up, and the bullet leaves the rifle with an initial velocity magnitude of 525 m/s. After 4.15 s, the velocity is 482 m/s. At what rate (in m/s2) is the bullet decelerated? (Recall that a negative sign denotes negative acceleration, or deceleration.) Enter answer 2 A rock thrown straight up climbs for 3.50 s, then falls to the ground. Neglecting air resistance, with what velocity (in m/s)...

(5 pts) You shoot a bullet at a vertical target that is a uniform mass M and moment of inertia l (1/2)MR. The target is free to rotate without friction about the hanging point P that is at the edge of the target as shown. Bullet has mass m, very small radius comparing to the target and moment of inertia le. Bullet is spinning about the line of travel at...

Quickly answer all parts of the question please
Problem 3 (4 pts.). A bathyscaphe (a small free-diving self-propelled deep-sea submersible), is a sphere of radius R- 1.5 m located 873.5 m below the sea level. (a) What is the pressure exerted on its surface (here you can neglect the size of the bathyscaphe compared to the depth of its immersion) and the buoyant force acting on it in the water (6) If a small leak is opened at the top...

Question 2 3 pts A criminal is escaping across a rooftop and runs off the roof horizontally at a speed of 4.8 m/s. hoping to land on the roof of an adjacent building. Air resistance is negligible. The horizontal distance between the two buildings is D, and the roof of the adjacent building is 2 m below the jumping off point. Find the maximum value for D. 2 pts O Question 3 In developing its future strategy, CVS is focusing...

D | Question 2 1 pts A mass m slides up an incline (with 0 27.6 degrees above the horizontal) until it stops momentarily because of friction. The coefficient of static friction between the mass and incline is 0.7; the coefficient of kinetic friction between the mass and incline is 0.4. At a given instant, the mass is moving with speed of 7.1 m/s up the incline. How far beyond this point along the incline will the mass move before...
