Step 1
- Mass of the object, \( m = 1500 \, \text{kg} \). - The object is at rest at \( t = 0 \), so initial velocity \( u = 0 \, \text{m/s} \). - The graph shows force \( F \) in kilonewtons (kN) over time \( t \) in seconds. Show moreā¦

A time varying force $F=2 t^{2}$ is applied on a body of mass $10 \mathrm{~kg}$ the variation of force with time is graphically shown. (a) 'l'he speed of body at $t=5 s$ is $25 / 3 \mathrm{~m} / \mathrm{s}$ (b) Speed of body at $t=3 s$ is $1.8 \mathrm{~m} / \mathrm{s}$ (c) Velocity varies with time (d) Velocity is constant
