Review Learning Goal: To practice Problem-Solving Strategy 4.1 for projectile motion problems. A rock thrown with speed 12.0 m/s and launch angle 30.0° (above the horizontal) travels a horizontal distance of d 19.0 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/s for the free-fall acceleration. Find the height y, from which the rock was launched. Express your answer in meters to three significant figures.

Projectile Motion Problems for Student Practice Physics C Free Response Option #3 A projectile is launched from a level plane toward a 65 m high cliff. The cliff is 150 m away from the cannon. At launch, the projectile has a velocity of 80 m/s at an angle 55 above the horizontal. Air resistance is negligible. a) Draw a repeesentation of the trajectory of the peojectile (for this one, do this after you find out where it hits) b) Calculate...

Learning Goal: To practice Problem-Solving Strategy 9.1 A strategy for conservation of momentum problems. An 80-kg quarterback jumps straight up in the air right before throwing a 0.43-kg football horizontally at 15 m/s . How fast will he be moving backward just after releasing the ball? Part F Suppose that the quarterback takes 0.30 s to return to the ground after throwing the ball. How far d will he move horizontally, assuming his speed is constant? Answer in meters.
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....

A ball thrown horizontally with speed vi = 20.0 m/s travels a horizontal distance of d = 58.0 m before hitting the ground. From what height h was the ball thrown? When setting up projectile motion questions, which of the following characteristics of projectile motion are important to keep in mind? Check all that apply. a. Projectile motion is the motion of an object that moves in two dimensions under the influence of gravity and air resistance. b. Although the...
