A person could jump further on the moon than on the earth, because on the moon there is less gravity and our weight is less, so we can jump further. Hope this helps.
Given:
m(mass)=88kg
v(velocity)=10m/s
Now kinetic energy=1/2(mv^2)
Where m is the mass
v is the velocity
Substituting these values we get
Kinetic energy=1/2(88 X 10 x 10)
Kinetic energy = 4400 N
Answer:
a. same
b. less
c. same
d. same?
Explanation:
the mass will always be the same no matter where it is. the weight however depends on the gravity.
Answer:
15.71 m/s
Explanation:
We are given;
Time; t = 0.2 s
Radius; r = 0.5 m
The circumference will give us the distance covered.
Formula for circumference is 2πr
Thus; Distance = 2πr = 2 × π × 0.5 = π
Linear speed = distance/time = π/0.2 = 15.71 m/s
