Question

a cricket ball of mass 2 kg initially at rest, is acted upon by a force which causes it to move a distance pf 5 m in 3 s. calculate the force applied.

Answer 1

The force applied to the cricket ball can be calculated using Newton's second law by finding the acceleration and multiplying it by the mass of the ball. The force is found to be 3.34 N.

Step-by-step explanation:

To calculate the force applied, we can use Newton's second law which states that force (F) is equal to mass (m) multiplied by acceleration (a). The acceleration can be calculated using the formula v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time. In this case, the initial velocity (u) is 0 m/s, the final velocity (v) is 5 m/s, and the time (t) is 3 s. Therefore, the acceleration is (5 - 0) / 3 = 1.67 m/s².

Now, substituting the mass (m = 2 kg) and acceleration (a = 1.67 m/s²) into the formula F = ma, we can find the force. F = (2 kg)(1.67 m/s²) = 3.34 N.

So, the force applied to the cricket ball is 3.34 N.
