Below is a graph of paintball speeds vs. time for Tyler and Bree's paintball guns. Use this graph to answer the questions below.

For each paintball gun, describe weather the paintballs are speeding up, slowing down, or moving at a constant speed. Also, describe whether the rate of acceleration is increasing decreasing or there is no acceleration.

For each paintball gun, the speed and rate of acceleration is described as follows;

A) For tyler's paintball;

First 1 second; Speed is increasing and acceleration is also increasing.

From 1 second to 5 seconds; Speed was constant and there was no acceleration.

B) For Bree's paintball;

First Second; Speed is increasing and acceleration is also increasing.

From 1 second to 5 seconds; Speed was increasing and acceleration was also increasing.

Looking at the graph, the speed is on the y-axis while the time is on the x-axis.

a) For tyler's paintball, we see that for the first one second, the speed increased gradually from 0 m/s to 450 m/s.

This means acceleration here was; a = speed/time = 450/1 = 450 m/s²

Thus paintball was speeding up while rate of acceleration was increasing for the first 1 second of the motion.

From this 1 second to 5 seconds, the speed was constant at 450 m/s.

This means there is no acceleration since speed is constant

b) For bree's paintball, we see that for the first one second, the speed increased gradually from 0 m/s to 450 m/s.

This means acceleration here was; a = speed/time = 450/1 = 450 m/s²

Thus paintball was speeding up while rate of acceleration was increasing for the first 1 second of the motion.

From this 1 second to 5 seconds, the speed is gradually increasing from 450 m/s to 700 m/s. Thus, acceleration will also be increasing as well.
