A particle moves along a coordinate axis with the positive direction to the right Its position at time t is given by s t t 2t 3 Find v 1 and a 1 and use these values to answer the following questions a What is v 1 v 1 b Is the particle moving from left to right or from right to left or neither at time t 1 O right to left O neither O left to right c What is a 1 a 1 d Is the particle speeding up or slowing down or neither at time t 1 Carefully think about the signs of the velocity and acceleration when t 1 before responding to this part O neither O speeding up slowing daun
