Malaan is travelling from Makhado to Polokwane by taxi at a speed of 120km/h.A Nissan bakkie passes the taxi while it is on its way to Polokwane and is moving at 150km/h.
a) Determine Malaan's velocity with respect to the Nissan bakkie
b) what is the taxi 's velocity with respect to bakkie?
C)suppose both the taxi and the bakkie were moving in different directions.Determine the bakkie's velocity with respect to the taxi.
Can someone help plz
120 - 150 = -30
-150 - 120 = -270
To determine the velocities with respect to each other, we need to subtract the velocities. Velocity is a vector quantity, which means it has both magnitude and direction. In this case, since they are moving in one dimension (along a straight line), we will consider only the magnitudes.
a) To determine Malaan's velocity with respect to the Nissan bakkie:
We subtract the velocity of the bakkie from the velocity of the taxi:
Malaan's velocity = Taxi's velocity - Bakkie's velocity
= 120 km/h - 150 km/h
= -30 km/h
Therefore, Malaan's velocity with respect to the Nissan bakkie is -30 km/h, indicating that Malaan is 30 km/h slower than the bakkie.
b) To determine the taxi's velocity with respect to the bakkie:
We subtract the velocity of the taxi from the velocity of the bakkie:
Taxi's velocity = Bakkie's velocity - Malaan's velocity
= 150 km/h - (-30 km/h)
= 150 km/h + 30 km/h
= 180 km/h
Therefore, the taxi's velocity with respect to the bakkie is 180 km/h, indicating that the taxi is moving 180 km/h faster than the bakkie.
c) Suppose both the taxi and the bakkie were moving in different directions. To determine the bakkie's velocity with respect to the taxi:
We add the velocity of the bakkie to the velocity of the taxi:
Bakkie's velocity = Taxi's velocity + Malaan's velocity
= 120 km/h + (-150 km/h)
= -30 km/h
Therefore, the bakkie's velocity with respect to the taxi is -30 km/h, indicating that the bakkie is moving 30 km/h slower than the taxi.
