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.
Answer:
V = 1.02 m/s
Explanation:
Given that,
The mass of a steel ball, m₁ = 3 kg
The mass of glob of clay, m₂ = 4 kg
The speed of a steel ball, u₁ = 2.4 m/s
The speed of glob, u₂ = 0 (at rest)
Let V be the combined speed of the system. Using the conservation of energy to find the combined speed.
So, the combined speed is 1.02 m/s in left direction.
