Answer:
a. Acceleration = 1.75 m/s²
b. Force = 105 Newton.
Explanation:
<u>Given the following data:</u>
Mass = 60kg
Final velocity = 7m/s
Time = 4 seconds
Required to find the acceleration and force of the body;
a. To find the acceleration;
Mathematically, acceleration is given by the equation;
Where;
- a is acceleration measured in
- v and u is final and initial velocity respectively, measured in
- t is time measured in seconds.
Since the elevator is starting from rest, its initial velocity is equal to 0m/s.
Substituting into the equation, we have;
<em>Acceleration = 1.75 m/s²</em>
b. To find the force;
Substituting into the equation, we have;
<em>Force = 105 Newton. </em>
