Question

1. A car starts at position x = 0,with an initial velocity of 2.6 m/s and an acceleration of 0 m/s2. What is its position when the elapsed time is 9.5 s? (Please be sure to include units in your answer. Express your answer to one decimal point.)

2.A car has an initial position of x = 0 m, an initial velocity of 0 m/s, and a constant acceleration of 4.7 m/s2. What is its position when the time is 2.7 seconds? (Please be sure to include units in your answer. Express your answer to one decimal point.)

3.A car has an initial position of x = 0 m, an initial velocity of 0 m/s, and a constant acceleration of 5.1 m/s2. What is its velocity when the time is 5.2 seconds? (Please be sure to include units in your answer. Express your answer to one decimal point.)

Explanation / Answer

1. x= u*t+1/2(a)(t^2)=2.6*9.5+0=24.7 m

2. x= u*t+1/2(a)(t^2)= 0+0.5*4.7*2.7^2=17.1 m

3. v= u+at= 0+5.1*5.2=26.5 m
