- A remote-controlled car is moving around in a level (horizontal) parking lot. The velocity of the car as a function of time is given by: 3 = [5.0m/s – (0.018m/s³)t²]î + [2.0m/s + (0.55m/s²)t]j where î and ĵ are unit vectors representing two perpendicular directions on the horizontal ground (think of them as the East and North directions, if that helps you). b). What are the magnitude and direction of the car's velocity at t = 8.0 s? c). What are the magnitude and direction of the car's acceleration at t = 8.0 s? (Don't be intimated by the velocity function! Look at the î and ĵ components, and work each component separately to begin with, before combining components together to get any resultant vectors, if needed.)arrow_forwardProblem 3: An arrow is shot from a height of 1.8 m toward a cliff of height H.

- Consider a projectile being launched with an initial speed of 43 m/s at a variety of initial angles. Refer to the figure. What is the range, in meters, of the projectile if it is launched at an angle of θ1 = 79.7°? What is the range, in meters, of the projectile if it is launched at an angle of θ2 = 40.5°? What is the range, in meters, of the projectile if it is launched at an angle of θ3 = 90 − 79.7°, the complement of θ1?arrow_forwardThis problem will involve deriving a formula or two for a projectile launched from one height and angle and landing at a different height on Earth. Begin with a projectile launched at angle 0 above horizontal from a height y₁ with initial velocity Vo. The projectile lands at a point with height y₂. These are the given quantities: vo, 0, y₁, y2 and g. Construct formulae for each of the following, as. a function of given quantities the horizontal distance traveled. the maximum height reached. the time taken. the angle of impact. (find the final velocity components first).arrow_forwardAsaparrow_forward

- Spitting cobras can defend themselves by squeezing muscles around their venom glands to squirt venom at an attacker. Suppose a spitting cobra rears up to a height of 0.440 m above the ground and launches venom at 3.70 m/s, directed 39.0° above the horizon. Neglecting air resistance, find the horizontal distance (in m) traveled by the venom before it hits the groundarrow_forwardQuestion: Diego is getting hungry and acting like a typical saber-toothed tiger. He visualizes Sid as a hunk of meat and begins to chase him frantically around the ground. First, Sid darts 50.0 meters at 35.0° NoW and then turns abruptly and races 40.0 m S. If Manny ran from where they were originally standing to where Sid ended up, how far and in what direction would Manny have to run to break up the fight? Use the triangle method to solve this. Should you use the component method, I will award zero points. I know the answer I just don’t know how to get it.
