Question

Justine is ice-skating at the Lloyd Center. What is her final velocity if she accelerates at a rate of 2.0 m/s^2 for 3.5 seconds?

Answer 1

Answer:

7m/s (assuming u = 0)

Explanation:

v = ?

u = 0

t = 3.5 a

a = 2m/s^2

v = u + at (first equation)

v = 0 + 2 x 3.5

v = 7

hopefully it helped

Answer 2

From the given question the correct answer is:

7m/s is her final velocity if she accelerates at a rate of 2.0 m/s^2 for 3.5 seconds

7m/s (assuming u = 0)

Solution:

7m/s (assuming u = 0)

v = ?

u = 0

t = 3.5 a

a = 2m/s^2

v = u + at (first equation)

v = 0 + 2 x 3.5

v = 7
