Q. Lillian has had enough of Tiffany's antics and runs over to Tiffany's table. With an initial speed of 2m/s, Lillian accelerates at a rate of 18m/s2 for 1.5 seconds, what is her final speed?A. 29m/sB. 35m/sC. 19m/sD. 23m/s
Identify Given Values: Identify the given values and the formula to use.Given values:Initial speed u = 2 m/sAcceleration a = 18 m/s2Time t = 1.5 sWe will use the formula for final velocity v in uniformly accelerated motion: v=u+at
Substitute Values into Formula: Substitute the given values into the formula. v=u+atv=2m/s+(18m/s2×1.5s)
Perform Multiplication: Perform the multiplication to find the change in speed.Change in speed = 18m/s2×1.5sChange in speed = 27m/s
Find Final Speed: Add the change in speed to the initial speed to find the final speed.v=2m/s+27m/sv=29m/s
