what is the effect of increasing the time of impact on force?
a decreases the force experienced b has no effect on the force experienced
c doubles the force experienced d increases the force experienced

Explanation:

To determine the effect of increasing the time of impact on force, we use the impulse - momentum theorem, which is expressed as \(J = F\Delta t=\Delta p\) (where \(J\) is impulse, \(F\) is force, \(\Delta t\) is the time interval, and \(\Delta p\) is the change in momentum). If the change in momentum (\(\Delta p\)) remains constant (for example, in a collision where the mass and the change in velocity are fixed), and we increase the time of impact (\(\Delta t\)), from the formula \(F=\frac{\Delta p}{\Delta t}\), we can see that force \(F\) and time \(\Delta t\) are inversely proportional. So, when the time of impact (\(\Delta t\)) increases, the force \(F\) experienced will decrease.

Answer:

A. Decreases the force experienced
