Answer:
52 N
Explanation:
Given:
Work done= 1820 J, distance= 35 meters Force = ?
Formula for work done
W = F • d
Find F.
F = W / d
Substitute the given into the equation.
F = 1820 J / 35 m
= 52 N
Answer:
V= 14.2m/s
Explanation:
We know that acceleration= dv/dt
So 16m/s²=dv/ dt = v dv/ds
So this wil be
Integral of 16m/s² ds [at 2,2]= integral of v dv at[ 0, v]
So 16[s (3/2)/3/2] at ( s,3) = v²/2
At s= 6m
So v² = 64/3( 6^1.5-3^1.5)
= 14.2m/s
compression happens before ignition so it would be step 2
