The answers to all three questions depend on WHICH branch
of Physics you're talking about . . . a piece of information you've
neglected to specify.
The resulting expression for the product of 1.58 and 0.03 is 0.05
The resulting expression for the sum of 1.4 and 2.53 is 3.9
The resulting expression for the sum of 2.34 x 10² and 4.93 is 2.39 x 10²
Given the following expression
(a) 1.58 x 0.03
taking the product
Converting too 1 significant figure
b) 1.4 + 2.53
1.4 = 14/10
2.53 = 253/100
Find their sum
c) 2.34 x 10² + 4.93
Given that
4.93 = 4.93 × 10⁰
Hence;

First start by finding the acceleration experienced by the force. Then use the acceleration and a suvat equation to solve for distance.
Absorb kinetic energy and soften potentially damaging blows.
