A cannon is elevated at an angle of 30 degrees and fires a cannonball with a speed "v1". The Cannon is on top of a cliff with a height of "h". Given v1 and h, determine: a) The speed of the cannoball when it is at its maximum height. b) The speed of the cannonball just before hitting the ground. c) The angle the cannonball's velocity makes with the horizontal just before hitting the ground. d) The horizontal distance the...

A shot putter projected a shot at the angle of 28 degrees at a velocity of 47 fps. The shot was released from 7 ft from the ground. a. Compute the velocity in the y and x direction (in fps). b. Compute the time from release of the shot put to the highest point. c. Compute the time from the highest point to the ground. d. Determine the total time the shot traveled while in the air. e. How far...

A cannonball is launched with a velocity of 52.5 ms at an angle of 47.2◦ above the horizontal on a flat firing range. Ignoring air resistance for every part, determine (a) the maximum height reached by the cannonball, (b) the total time in the air, (c) the total horizontal distance covered, (d) and the speed and direction (angle) of the cannonball 1.50 s after firing.

A shot putter threw a shot at an angle of 43o above the horizontal from a height of 2.0 m above the ground. The shot traveled 19.0 m horizontally from the launch position. (a) What was the initial speed of the shot when it left the shot putter’s hand? (b) How long was the shot in the air? {13.0 m/s, 2.0 s}

A spherical cannonball of mass 2M is launched with an initial velocity v0 at an angle...

A spherical cannonball of mass 2M is launched with an initial velocity v0 at an angle of 45° above the horizontal. There is an explosive charge between the two halves of the cannonball which is detonated when the cannonball has reached the highest point of its trajectory. One half of the cannonball (mass M) is propelled backwards exactly along the original trajectory and lands back in the cannon (good trick!). Ignore air resistance for this problem. a) Assuming level terrain,...

A cannon is shot at 48 m/s at an angle of 30 degrees to the horizontal off a cliff that is 78.4 meters tall. How fast will the cannonball be moving when it hits the ground at the bottom of the cliff?

2. A pendulum exhibits simple harmonic motion when it is released at an angle θ = 9°. The length of the pendulum is l=0.86 m, and the pendulum bob has a mass m=0.3 kg. a. What is the pendulum’s frequency? b. Use energy conservation to find the pendulum bob’s speed when it passes through the lowest point of the swing? Assume that the difference in height between the lowest part of the swing and the highest part of the swing...

Imagine an example of projectile motion in which the launch angle is 30o above the horizontal, the launch position is 3 m above the ground, and the launch speed is 15 m/s. Where could you place a target on the ground so that it will “catch” the projectile when it lands?

Projectile Motion - Rocket Clears Wall - General Launch Angle A rocket is fired at an initial speed v0 = 165.0 m/s from ground level, at an angle θ = 50° above the horizontal. A wall is located at d = 67.0 m. Its heigh is h = 47.0 m. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as psotitive y-direction Find v0x, the x component of the...
