What is the velocity vector? The equation r(t) = (2t + 5) i + (t² − 1) j + (t) k is the position of a particle in space at time t. Find-the particle's velocity and acceleration vectors. Then write the particle's velocity at t = 1 as a product of itsspeed and direction.

The velocity vector of a particle is the derivative of the position vector. Given the position…

The kinetic energy E of an object varies jointly with the object’s mass m and the square of the object’s velocity v . An object with a mass of 50 kilograms traveling at 16 meters per second has a kinetic energy of 6400 joules. What is the kinetic energy of an object with a mass of 70 kilograms traveling at 20 meters per second?
A projectile is fired straight up from a platform 10ft above the ground, with an initial velocity of 160 ft/sec. Assume that the only force affecting the motion of the projectile during its flight is from gravity, which produces a downward acceleration of 32 ft/sec?. What is the equation for the height of the projectile above the ground as a function of time t if t = 0 when the projectile is fired? s = -16t2 + 80t + 10 s = 16t2 – 160t + 10 - O D A s = -16t2 – 160t + 10 s = -16t2 + 160t + 10 B
Determine the particular equation for the velocity if the acceleration is given by the equation a = 9t2 + 8t + 3 where v = 50 when t = 2. Express your answer in the form At3 + Bt2 + Cx + D.
