Answer:
C
Explanation:
Acceleration is defined as a change in velocity over time. This means that as long as the forces are not zero, the velocity should be changing. The can be negative (as this is negative acceleration also known as deceleration) or positive (known as acceleration). It doesn't matter if they are decimals or fractions.

<em>1</em><em>.</em><em> </em><em>as </em><em>the </em><em>object </em><em>is </em><em>stationary </em><em>despite </em><em>Jamal </em><em>applying </em><em>100N</em><em> </em><em>forces</em><em>, </em><em>it </em><em>suggests </em><em>that </em><em>the </em><em>object </em><em>i</em><em>s </em><em>applying </em><em>an </em><em>equal </em><em>amount </em><em>of </em><em>force </em><em>on</em><em> </em><em>the </em><em>opposite</em><em> </em><em>direction </em><em>that </em><em>is </em><em>opposing </em><em>the </em><em>force </em><em>applied</em><em> </em><em>by </em><em>Jamal.</em>

vf ^2 = kx^2/m = 56(0.75)^2 / 2.5 = 12.6
Therefore, v= 3.5 m/s.
Answer:
50 kg
Explanation:
Given,
Force ( F ) = 100 N
Acceleration ( a ) = 2 m/s^2
To find : Mass ( m ) = ?
Formula : -
F = ma
m = F / a
= 100 / 2
m = 50 kg
Therefore, the mass of the object is 50 kg.
