What is the start velocity of a javelin accelerated at 3.75 m/s2 for 2 seconds, and reaching 9375 m/s?

Step-by-step explanation:

u = ?

a = 3.75m/s^2

t = 2 s

v = 9375m/s

a = v-u/t

3.75 = 9375 - u / 2

3.75 × 2 = 9375 - u

7.5 = 9375 - u

u = 9375 - 7.5

= 9367.5 m/s

Hope this helps

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
