Answer:
100 J
Step-by-step explanation:
Kinetic energy is jointly proportional to mass and the square of the velocity.
KE = 1/2mv²
KE = 1/2(50 kg)(2 m/s)² = 100 J
Juan has a kinetic energy of 100 joules.
Answer:
7.07 ft2
Step-by-step explanation:
As, Area of circle = πr^2
Here r is the radius
= π x 1.5^2
