Question

a car travels with a velocity 10 ms-1 and accelerates at 5ms-2 calculate the final velocity when it has travelled 30 m?​

Answer 1

Answer:

20 ms-1

Explanation:

u (initial velocity) = 10 ms-1

a= 5 ms-1

s= 30m

v^2 = u^2+2as

v^2= 10×10+2×5×30

v^2 = 100+300

v^2 = 400

v^2 =√400

v = 20m/s
