Question

Calculate the force exerted on the blown dart. A dart weighing 0.0056kg is blown and travels 4.85m. The change in velocity for the dart is 11.4m/s.

Answer 1

0.15N

Explanation:

Given data

Mass= 0.0056kg

distance= 4.85m

Velocity= 11.4m/s

The expression for the force is

F= mv^2/r

substitute

F= 0.0056* 11.4^2/4.85

F= 0.0056*129.96/4.85

F= 0.727776/4.85

F= 0.15N

Hence the force is 0.15N
