At a height h = 44.0 m above the ground a rocket is fired at an initial speed v0 = 168.0 m/s at an angle θ = 27 degrees above the horizontal. 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. Keep 2 decimal places in all answers (a) Find v0x, the x component of the initial velocity (in m/s) (b) Find v0y, the y component...

A faulty model rocket moves in the xy-plane (the positive y-direction is vertically upward). The rocket's acceleration has components ax(t)=αt2 and ay(t)=β−γt, where α = 2.50 m/s4, β = 9.00 m/s2, and γ = 1.40 m/s3. At t=0 the rocket is at the origin and has velocity v 0=v0xi^+v0yj^ with v0x = 1.00 m/s and v0y = 7.00 m/s. a. Calculate the velocity vector as a function of time. Express your answer in terms of v0x, v0y, β, γ, and...

A particle starts from the origin at t = 0 with an initial
velocity of 5.0 m/s along the positive x axis. If the acceleration
is (–3.0i + 4.5j) m/s^2, determine the velocity and position of the
particle at the moment it reaches its maximum x coordinate.
Can someone explain why
when the particle reaches it maximum x coordinate?

A particle with mass 4.0 kg is initially at rest at the origin (x=0). It then moves along the x-axis acted on by a force F(x)=18.0-2.0x2, where F is in Newtons if x is expressed in meters. Find the kinetic energy of the particle when it reaches x=3 m. A Honda Civic (mass=1090 kg) is initially traveling due East at 18.3 m/s when it suddenly collides head on with a Toyota Camry (mass=1612 kg) initially traveling due West at 31.8...
