Question

John Adams then activates the nitro boost, increasing the acceleration to 22 m/s2, and jams the steering column with a bar to keep the vehicle moving a straight line. If the vehicle is 170 meters behind the cargo plane that is heading down the runway at 20 m/s, how long in seconds does it take for the vehicle to pass the plane and for the second US president to jump onboard

Answer 1

Answer:

Explanation:

velocity of vehicle u = 20 m/s

acceleration a = 22 m /s²

distance s = 170 m

time t = ?

s = ut + 1/2 a t²

170 = 20 t + 1/2 x 22 t²

170 = 20t + 11 t²

11 t² + 20 t - 170 = 0

t = 3 s
