Answer:
The work done by Joel is greater than the work done by Jerry.
Explanation:
Let suppose that forces are parallel or antiparallel to the direction of motion. Given that Joel and Jerry exert constant forces on the object, the definition of work can be simplified as:
Where:
- Work, measured in joules.
- Force exerted on the object, measured in newtons.
- Travelled distance by the object, measured in meters.
During the first 10 minutes, the net work exerted on the object is zero. That is:
In exchange, the net work in the next 5 minutes is the work done by Joel on the object:
Hence, the work done by Joel is greater than the work done by Jerry.
Answer:
The distance traveled by the ball before it lands in the other player's glove is 130.96 m.
Explanation:
Given;
angle of projection of the ball, θ = 40⁰
initial velocity of the ball, u = 36.1 m/s
The distance traveled by the ball before it lands in the other player's glove is the range of the projectile, calculated as follows;
Therefore, the distance traveled by the ball before it lands in the other player's glove is 130.96 m.
