In the latest Indian Jones film, Indy is supposed to throw a grenade from his car, which is going 99.0 km/h , to his enemy's car, which is going 115 km/h . The enemy's car is 17.0 m in front of the Indy's when he lets go of the grenade. A If Indy throws the grenade so its initial velocity relative to him is at an angle of 45 ∘ above the horizontal, what should the magnitude of the initial velocity be? The cars are both traveling in the same direction on a level road. You can ignore air resistance. B Find the magnitude of the velocity relative to the earth.

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 person swings from a trapeze, projects herself at angle of 53 degrees, and is supposed to be caught by person B, whose hands are 6.1m above and 8.2m horizontally from persob A's launch point.  a. What initial speed must Person A have just to reach person B? b. If person B misses person A completely as she flies past, how far horizontally does person A travel, from her initial launch point, before landing in the safety net 8.6m below her starting point?

You buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizontal range. You shoot the gun straight up, and it takes 4.0 ss for the dart to land back at the barrel.     Part A What is the maximum horizontal range of your gun?

A canoeist, capable of travelling at a speed of 4.5 m/s in still water, is crossing a river that is flowing with a  velocity of 3.2 m/s [E]. The river is 2.2 x 102 m wide. Use component vectors from this course (not i and j vectors) .  Q ) If the canoe is aimed northward, where is the landing position of the canoe relative to its starting position and what is the displacement of the canoeist?

P In the movie Avengers, Hawkeye fires an arrow with a cable attached to a building after jumping from it to avoid an explosion. If he fires the arrow 5 m away and 8 m below the top of the building, with a velocity of 100 m/s and a slope of 12:5, determine the horizontal distance the arrow will travel from his initial point of firing to the point where it hits the top of the building. Prove using equations of projectile motion that the arrow will not hit the top corner of the building Please provide diagrams too, thank you

r The speed of a boat in still water is V. A river flows with a speed of v₁. The boat travels distance of 14 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the V and V₁. Hint: Velocity = displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "V" and "v": Do V" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative. Equation 1 (downstream): Equation 2 (upstream): Solve for: V₁² vb Write an algebraic expression; do not use numerical values except…

You have exactly 4 minutes 26 seconds to get to your next class on time and that classroom is 216 m east of where you are right now. First you run to your dorm room at an average velocity of 5.42 m/s to the south to pick up your calculator and your dorm room is 332 m south of where you were initially. What average velocity (magnitude only) do you now need to run from your dorm room to your classroom to arrive exactly on time?   a. 1.49 m/s   b. 5.42 m/s   c. 1.93 m/s   d. 2.06 m/s

a. A football player kicks a ball at an initial velocity of 15 m/s at an angle of 30° with horizontal. Find the time of flight, range, maximum height, and velocity components at t = 0, at mid-range and at impact.
