A race car has an initial speed of vo = 51 m/s when the driver releases a drag parachute. If the parachute causes a deceleration of - 5 m/s, how far will the car travel, in meters, before it stops? Please round your answer to the nearest whole number (integer).A pitcher delivers a fast ball with a velocity of - 22 m/s (to the south). The batter hits the ball and gives it a velocity of + 99 m/s (to the north). What is the average acceleration (in m/s2 ) of the ball during the 34 ms when it was in contact with the bat? Note that 1.0 ms = 10-3. Please round your answer to the nearest whole number (integer).A jogger runs along a straight and level road for a distance of 12.0 km and then runs back for a distance of 4.0 km. The time for this round trip is 2.0 h. Which one of the following is true? O Her average speed is 7.0 km/h, and her average velocity is 1.0 km/h. O Her average velocity is 4.0 km/h, and her average speed is 8 km/h. O Her average speed is 8.0 km/h, but there is not enough information to determine her average velocity. O Her average speed is 12.0 km/h, and her average velocity is 8.0 km/h. O Her average speed is 2.0 km/h, and her average velocity is 0 km/h
