Complete question:

A dragster starts from rest and accelerates at 35 m/s2 m / s 2 . How fast is it going after 7s.

Answer:

The final velocity of the dragster is 245 m/s.

Explanation:

Given;

acceleration of the dragster, a = 35 m/s²

initial velocity of the dragster, u = 0

time of motion, t = 7 s

the final velocity of the dragster after 7s is given by;

v = u + at

where;

v is the final velocity

u is the initial velocity

v = 0 + (35 x 7)

v = 245 m/s

Therefore, the final velocity of the dragster is 245 m/s.

Hence, superficial anatomy is also popularly referred to as surface anatomy.

In this scenario, a patient arrives at an emergency room complaining of pain in her ankle. The nurse examines the patient’s ankle, looking for skin discoloration or swelling. The nurse is relying mostly on his knowledge of superficial anatomy by studying or examining the patient's ankle for any sign of decoration or swelling on the skin.
