Looking For: Equation: x = xo + vo t + ½ at2 Final position Given: xo = -8 m vo = 2 m/s t =3 s x = -8 + 2*3 + ½ 1*32 a= m/s/s x = 2.5 m Problem 23) A penny is dropped from the Empire State Building downward. It starts at position 0m. Its starting velocity is 0 m/s. It accelerates at 10 m/s2. How far has it fallen after 2 seconds (find x)? Looking For: Equation: position x = xo + vo t + ½ at2 Given: Solve: xo = 0 m vo = 0 m/s t = 2s x = 0 + 0*2 + ½ 10*22 a= 10 m/s2 x=20 m Calculating Acceleration from Position Data Tables and Motion Diagrams Calculating Acceleration from Position using Data Tables and Motion Diagrams Problem 24: Speed = _____ ______ ________ ________
