To determine The direction and magnitude of the average force exerted on the puck. Explanation Figure 1 Figure 1 shows the schematic of object incident with u and emerges with v making an angle 45 ° with each other. Write the expression for the force acting on the object. F → = m a → (I) Here, F is the force, m is the mass, a is the acceleration of the object. Write the expression for the a → . a → = v → − u → t (II) Here, v is the final velocity, u is the initial velocity, t is the time. Write the expression for the u → . u → = u i ^ (III) Write the expression for v → . v → = v cos θ i ^ + v sin θ j ^ (IV) Here, θ is the angle between u → and v → . Use equation (III) and (IV) in (II) to solve for a → . a → = ( v cos θ i ^ + v sin θ j ^ ) − ( u i ^ ) t (V) Use equation (V) in (I) to solve for F → . F → = m [ ( v cos θ i ^ + v sin θ j ^ ) − ( u i ^ ) t ] = m [ ( v cos θ − u ) i ^ − ( v sin θ ) j ^ t ] (VI) Write the expression for the F . F = ( m ( v cos θ − u ) t ) 2 + ( m ( v sin θ ) t ) 2 (VII) Conclusion: Substitute 166 g for m , 112 ms for t , 45 ° for θ , 44
