What distance does he cover after 3s?(the complete question is in the picture) An object moves with positive constant acceleration from t = 0 to t = T.Which of the following is TRUE about its instantaneous (a) and average (aave) accelerationin this time interval?A. a > aaveB. a < aaveC. a = aaveD. a =aave2sketch a graph of velocity vs time for the 12 second time interval An object starts at x = 0 with an intial velocity of -2 m/s and moves in astraight line along the x-axis. The graph shows its acceleration as a functionof time
- what is the initial velocity of an object that slows to rest in 2.0 sec at 45 m/s2?A train of has a maximum speed of 50 km/hr and its acceleration and deceleration are limited to a maximum rate of 2.222 m/s^2. How much time does it take for the train to accelerate and achieve its maximum speed and then decelerate to a halt?During a race, you are running at a speed of 4.50 m/s. You want to pass a slowerrunner, so you increase your speed steadily (that is, with constant acceleration) to5.75 m/s over a time period of 3.00 s. What was your acceleration over this timeperiod, and what distance did you travel between when you started and ended theacceleration? When taking off, a commercial airliner starts from rest and attains a velocity of81.0 m/s over a distance of 1.50 km. Assuming that it accelerates at a constantrate, what is this rate of acceleration?

She then observes a slow-moving van 160 m ahead traveling at 5.40 m/s. Sue applies her brakes but can accelerate only at −1.80 m/s2 because the road is wet. how far into the tunnel and at what time will a collision occur?
