Initial gap between point A and cyclist is 150m
distance travelled at constant velocity of 7m/s for 45 sec is
D=v*t
D=distance
v=velocity
t=time
Therefore; distance travelled is 315m
total gap is distance travelled + initial gap=150+315=465m
<span>the cyclist’s position from point A at 45s is 465m</span>
Answer:
HELLO! I WILL EXPLAIN WHY GOLF BALLS HAVE DIMPLES.
Explanation:
