A car traveling in a northeasterly direction at a rate of 50 km/h represents which of the following? A.
deceleration
B.
velocity
C.
speed
D.
acceleration

c.

Explanation:

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.

Formula

s = \frac{d}{t}

s=speed

d=distance traveled

t=time elapsed

good looking response

need to see circuit to get time constant
