:i don't know how to do these problems if a driver is driving his car towards tulsa and has to accelerate onto the highway if the ramp is 2000.0m long and he needs to reach a speed of 29.00m/s from his current speed of 10.0m/s. if his acceleration is constant, how long will it take him to reach that speed? a sprinter needs to get to max velocity as soon as possible. if he starts at the 30.0m point and runs the 100.0m in 11.2s if the average speed of the last 70.0m is 9.85m/s what is the acceleration? katheryn is riding her horse which is walking along at 5.00m/s and she needs to get to the stable in 40.0s before the rain comes. it is 500.0m away. what will she need to accelerate at to get there in time? if dillon can get his car to accelerate at 2.2m/s squared and needs to get from 10.0m/s to 35.0m/s how long will it take? how far will he have travelled in that time?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
