P1.A cannonball is shot at an angle of 45" with an initial velocity vo. This is calculated to exactly land at point B in a projectile trajectory. However, the people at point B launched a rocket with an initial ve locity at 20 from the horizontal sometime after the cannonball launched. The rocket, which will intercept the cannonball at some vertical distance from the ground level, is in a linear path, Find (a) horizontal distance between point A and Point...

A ball is shot from the ground into the air. At a height of 9.80 m, its velocity is v = (8.50i + 4.00j) m/s, with i horizontal and j upward. To what maximum height does the ball rise? What total horizontal distance does the ball travel? What is the magnitude of the ball's velocity just before it hits the ground? What is the angle (below the horizontal) of the ball's velocity just before it hits the ground?
A soccer ball is kicked with an initial horizontal velocity of 20 m/s and an initial vertical velocity of 16 m/s
A soccer ball is kicked with an initial horizontal velocity of 20 m/s and an initial vertical velocity of 16 m/s. I've calculated: Initial Speed: 25.61 m/s Angle: 38.66 degrees Maximum Height it reaches: 13.06 m Distance kicked: 65.29m NOW I NEED: What is the speed of the ball 0.7 seconds after it was kicked? How high above the ground is the ball 0.7 seconds after it is kicked? help? please.

In the figure, a 0.400 kg ball is shot directly upward at initial speed 31.1 m/s. What is its angular momentum about P 8.65 m horizontally from the launch point, when the ball is (a) at maximum height and (b) halfway back to the ground? What is the torque on the ball about P due to the gravitational force when the ball is (c) at maximum height and (d) halfway back to the ground? Ball (a) Number O (b) Numbe...

The initial velocity of the boulder is Vo = 40 m/s and it is released at an angle ofa-55° above the horizontal as shown in the diagram below. Assume that the boulder is released at ground level at position 0. The projectile reaches its maximum height at position 1 and lands at its target at position 2. Given that the desired target is at a height of h2 - 30 m above ground level, calculate each of the following values...

A soccer ball is kicked with an initial horizontal velocity of 18 m/s and an initial vertical velocity of 13 m/s. 1) What is the initial speed of the ball? 2) What is the initial angle ? of the ball with respect to the ground? 3) What is the maximum height the ball goes above the ground? 4) How far from where it was kicked will the ball land? 5) What is the speed of the ball 0.8 seconds after...
a ball with mass 0.15 kg is thrown upward with initial velocity 20 m/sec from the roof of a building 30 m high
a ball with mass 0.15 kg is thrown upward with initial velocity 20 m/sec from the roof of a building 30 m high. there is a force due to air resistance of |v|/30, where velocity v is measured in m/sec.a. find the maximum height above the ground the ball reaches.b. find the time the ball hits the ground.you cannot use the kinematic equations.
