Question

A net force F exerted on a 22 $kg$ block. A graph is drawn between force versus time in seconds as shown in the given graph. The acceleration of the block between $0$ and $2$ seconds is :

• A. $7.5m/s^2$
• B. $3m/s^2$
  
• C. $4m/s^2$
  
• D. $1.5m/s^2$
• E. $9m/s^2$
  

Answer 1

The correct option is D

$1.5m/s^2$

From the given graph, $F=2N$ for time $0$ to $2$ seconds.

$a=\frac{F}{m}=\frac{3N}{2kg}=1.5m/s^2$
