What is the minimum work needed to push a 970-kg car 320 m up along a 8.5 ∘ incline? Ignore friction.

Express your answer using two significant figures.

science physics

Answer 1

Answer #1

Workk done=force×distance

= m*g*Δh

W=970*9.8*320*sin 8.5°

W=449624.4 J

W=450000 J in two significant no
