The velocity of a ball in the horizontal direction is given as the following function: v(t) = 20 + 3t3,where t is in seconds and the velocity is in meters per second. part (a) find the change in the position, in meters, between t = 0 and t = 5.5 s. part (b) find the acceleration in the horizontal direction, in meters per square second, at t = 0.part (c) find the acceleration in the horizontal direction, in meters per square second, at t = 5.5 s.

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

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.

If a tank filled with water contains a block and the height of the water above point a within the block is 0.8 meter, what is the pressure at point a?
