1. What force is needed to accelerate a child on a sled( total mass `= 60.0 kg` ) at `1.25 m//s^2`?
1. What force is needed to accelerate a child on a sled( total mass = 60.0 kg ) at 1.25 m//s^2? `sum F = ma`
`sum F = 75.0 N`
Given:
`m = 60.0\ kg`
`a = 1.25\ m//s^2`
Known:
`F = ma`
Solution:
`F = (60.0\ kg)( 1.25\ m//s^2)`
`F = 75.0\ N` |
