7000 is a pure number, without dimensions. It cannot be compared or converted to any form of acceleration which has dimensions [LT-2].
The idea here is to use Newton's Law, F=ma. Solving for acceleration: a = F/m. The number of seconds is irrelevant if all you want to calculate is the acceleration.

105015% of 7000= 15% * 7000= 0.15 * 7000= 1050
2.8% of 7000= 2.8% * 7000= 0.028 * 7000= 196
7000 - 22% = 78% of 7000 = 7000*78/100 = 5460
1% of 7000= 1% * 7000= 0.01 * 7000= 70
