Question

Two forces act on a 2.50 kg object, the gravitational force and a second, constant force. The object starts from rest and in 1.20 s
is displaced (5.50î – 3.30j) m. Write the second force in unit vector notation. (Enter your answer in kg · m/s. Assume the
gravitational force acts in the -ĵ direction.)
kg · m/s2
II

Expert Solution

Step 1

$mass of object (m) = 2.50 k g Gravitational force (\vec{F_{g}}) = m \times \vec{g} = 2.5 \times 9.8 (- \hat{j}) = - 24.5 \hat{j} Initial speed (\vec{u}) = 0 \frac{m}{s} Time (t) = 1.20 s e c o n d s displacement (\vec{d}) = 5.5 \hat{i} - 3.30 \hat{j} m$
