Answer:

(a) 3.5 m/s²

Let initial velocity =u and a(uniformacceleration)

,v= 180−7x

x=distance traveled

By applying third equation of motion,

v² = u² +2as

⟹(√ 180−7x )² =u² +2as

⟹180−7x=u² +2ax

On comparing both sides,

u² =180 and 2a=−7

⟹a=−3.5m/s ²

Step-by-step explanation:

hope it's help...❤️
