A driver moves with initial velocity of 40m/s accelerates uniformly at a rate of 12m/s2.  It attains a velocity 52m/s. calculate the distance covered during the journey.

The total distance covered is 46m

Explanation:

From the question, we have the following given parameters.

Initial Velocity = 40m/s

Acceleration = 12m/s²

Final Velocity = 52m/s

Required

Calculate the distance covered during the journey

The question can be solved using the following equation of motion.

v² = u² + 2as

Where

v = final velocity = 52m/s

u = initial velocity = 40m/s

a = acceleration = 12m/s²

s = distance = ?

By substituting the above values in the stated formula

v² = u² + 2as becomes

52² = 40² + 2 * 12 * s

2704 = 1600 + 24s

Subtract 1600 from both sides

2704 - 1600 = 1600 - 1600 + 24s

1104 = 24s

Divide both sides by 24

1104/24 = 24s/24

46 = s

Reorder

s = 46

Hence, the total distance covered is 46m

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
