3. A 142 g baseball is thrown at a speed of 42.9 m/s. What is the kinetic energy of the baseball at this moment?
1 answer:
Kinetic energy=1/2mv^2
=1/2(142*10^-3)(42.9)^2=130.6=131J

Answer:
Newtons 1st law of inertia
Explanation:
this is basically the same as volume, no?
So, 5.345*4.128*3.859=85.145
Explanation:
Use the equation F=m×a
F= 1500 N
M= 500kg
a= F/M
a= 1500÷ 500
a= 3m/s^2
10/70×360°
=51.4°
hope thus helps
