Question

The points with position vectors (6000i + 300j), (4000i - 800j), and (ai - 5200j) are collinear it:​

Answer 1

Answer:

Given:-

Initial velocity ,u = 20m/s

Final velocity ,v = 45m/s

Time taken ,t = 6s

To Find:-

Acceleration ,a

Solution:-

According to the Question

We have to calculate the acceleration of the car.

As we know that acceleration is defined as the rate of change in velocity.

a = v-u/t

where,

v is the final velocity

a is the acceleration

u is the initial velocity

t is the time taken

substitute the value we get

:\implies:⟹ a = 45-20/6

:\implies:⟹ a = 25/6

:\implies:⟹ a = 4.16 m/s²

Hence, the acceleration of the car is 4.16 m/s².
