The speed-time graphs of two cars are represented by $P$ and $Q$ as shown below
$(a)$ Find the difference in the distance travelled by the two cars (in $m$ ) after $4\, s$.
$(b)$ Do they ever move with the same speed ? If so when ?
$(c)$ What type of motion car $P$ and $Q$ are undergoing ?
The speed-time graphs of two cars are represented by $P$ and $Q$ as shown below
$(a)$ Find the difference in the distance travelled by the two cars (in $m$ ) after $4\, s$.
$(b)$ Do they ever move with the same speed ? If so when ?
$(c)$ What type of motion car $P$ and $Q$ are undergoing ?
$(a)$ Distance covered by car $P$ in $4 s =12\, m$ (Area under $v-t$ graph $)$
Distance covered by car $Q$ in $4\, s=12\, m$ (Area under $v-t$ graph $)$
So difference $=0$
$(b)$ Yes, at $t=2 s$
$(c)$ Car $P$ : uniform acceleration and car $Q$ : uniform motion
