An object has a mass of 5 kg. What force is needed to accelerate it at 6 m/s2? (Formula: F=ma)
2 answers:
Answer:
<h2>30 N.</h2>Explanation:
According to Newton's second law, a force applied to certain object will accelerate it, that's the meaning of the formula:
So, in this case, we don't have to analyse much, because all values are given, we just have to replace them and solve for F:
Therefore, the force needed to accelerate that mass is 30 N.

Answer:
d = 1.19 m
Explanation:
Given that,
The force applied by the ball, F = 39.6 N
The work done on the catchers glove is 47.5 J
We need to find the distance traveled by the ball. We know that,
Work done, W = Fd
Where
d is the distance traveled
So, it will cover 1.19 m.
