A cookie is thrown into the air with an initial velocity of 10 m/s at an angle of 30o above the ground. What is the velocity vector v when the cookie reaches its highest point of the trajectory?

I throw a ball to my dog at h = 1.8 m above the ground, with initial velocity v0 = 10.25 m/s at an angle θ = 31° above horizontal. Assume the ballencounters no air resistance, and use a Cartesian coordinate system with the origin located at the ball's initial position.a. My dog jumps up in the air and catches the ball at the same height that Ithrew it. Create an expression for the time, tf, the ball is in the air in terms of v0, θ, g, and h. b. Calculate the horizontal distance, d in meters, between me and my dog

A ball is thrown downward from the top of the building with a speed of 18.0 m/s at an angle of 30.0° to the horizontal. a) What are the horizontal and vertical components of the velocity the instant the ball is thrown? b) What are the horizontal and vertical components of the velocity 1.00 s after being thrown?

A lizard kicks a ball with an initial velocity of 10 m/s at an angle of 35º with the horizontal. What is the maximum height of the ball?

Rain is falling steadily, but there is no wind. You are on a bus that moves at 50.0 km/hr, and you see that the rain appears to be falling at an angle of 31o with respect to the vertical. What is the vertical velocity of the rain drops?

A daredevil is shot out of a cannon at 45.0° to the horizontal with an initial speed of 28.0 m/s. A net is positioned a horizontal distance of 48.0 m from the cannon. At what height above the cannon should the net be placed in order to catch the daredevil?

A circus performer throws a knife at a bound stagehand who is tied to a post. The knife is thrown at an angle of 17.8° below the horizontal with an initial speed of 3.11 m/s. The knife hits the post between the stagehand's feet, a distance of 0.63 m vertically below where it was released. How far from the post was the performer when she threw the knife? Select one: a. 0.81 m cross out b. 0.38 m cross out c. 0.17 m cross out d. 0.77 m cross out e. 0.65 m cross out Your answer is incorrect. The correct answer is: 0.81 m

An athlete in a long jump trial leaves the ground at an 80o angle and covers a horizontal distance of 8.7 m. The speed with which he can jump remains constant. What should he do to increase the horizontal distance of his jump? Explain why this would work.

A baseball player throws a baseball with an intial velocity of 39.0m/s at an angle of 40 above horizontal. The release point of the baseball is 2.00m above the ground. The baseball lands on the field. Ignore air resistance. Find the horizontal travel distance of the ball.
