A 50 kg mass is sitting on a frictionless surface. A 157N force pushes the mass for 4.2 seconds until the mass reaches the desired velocity. Calculate the impulse in N.s. Only put in the numerical value. Answer to 1 decimal place and do not write the unit in your answer.

Question

BlackTom AI · Accepted Answer

To find the impulse delivered to the mass, multiply the constant force by the time interval over which it acts. 
First, note that impulse I equals force F times time Δt: I = F × Δt. 
Here, F = 157 N and Δt = 4.2 s, so I = 157 N × 4.2 s.
Calculating the product: 157 × 4.2 = 659.4.
Therefore, the impulse is 659.4 N·s. Since the prompt asks for the numerical value only and to one decimal place, the value to report is 659.4 (without the unit).
