The acceleration of a particle moving only on a horizontal xy plane is given by, where is in meters per second squared and t is in seconds. At t 0, the position vector locates the particle, which then has the velocity vector. At t 4.

Try this out. Use a calculator! We can use the formula KE=0.5m*V^2. To find the kinetic energy (KE) of a payload of mass (m) 100 kg as it flies through the air at the velocity (v) of 55 m/s. (Multiply 0.5 x the mass x velocity squared.
