Question

If s=55 t=10 a=4
Find
S=ut + 1/2 at²​

Answer 1

Step-by-step explanation:

S=55 and T=10 and A=4(given)

applying formula,we get,

S = ut +1/2 at²

so, putting values

we get,

55 = u ×10 + 1/2 × 4×10²

55 = u × 5 × 4 × 100 ( we cut 2 in 1/2 with 10)

55 = 20u × 100 ( multiplying 5 and 4 and u )

20u = 55/100

u = 55/100×20

u = 11/400
