If a car has an initial speed of +15 meters/second and a constant acceleration of +1 meter/second2, how much distance will it travel in the first 10 seconds after the acceleration begins?

Asun-sized star will spend most of its lifetime as a: white dwarf red giant protostar main-sequence star

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

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
