1. Work out the speed of a car travelling:
2 answers:
Step-by-step explanation:
speed is a scalar quantity (which only needs a magnitude), and velocity is a vector quantity (needs a magnitude with a direction)
Here since they want the "speed" you can use the velocity formula, but without a direction.
A. v=100/10
v=10m/s
B. v=300/20
v=15m/s
C. v=700/35
v=20m/s
D. V=1000/200
v=5m/s
