Answer:
The answer is gravitational force
Explanation:
Answer: 10 m/2^2
F=ma
Explanation:
Force = 1000N
1 N is 1 (kg*m/s^2)
Mass = 100kg
F=ma
a = F/m
a = (1000kg*m/s^20/(100kg)
a = 10 m/s^2
KE= 1/2MV^2 - equation
KE= 1/2 (2 kg)(15 m/s)^2 - plug it to the equation
KE= (1 kg)(225 m/s) - multiply
KE= 225 J - Answer (letter D)
Hope this helps
Answer:
6 m/s
Explanation:
Well we can find acceleration a=v/t = (21-0)/7=3 m/s^2
vf=at+v0, use this equation to solve for the vf
vf=3(2)+0=6 m/s was its speed at 2s
