during the 1990 olympics, an all-time record shot put was made 23.12 m (75 ft 10.2 in.) if the athlete released the shot at a height of 2.25 m with a velocity 14.3m/s at an angle of 35.0° to the ground, what was its vector velocity when it impacted the ground at the end of its flight?

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
