What is the potential energy of a rollercoaster if it weighs 1000 kg and sits on a 110 m tall ride?
1 answer:
Answer:
11×10⁵ J
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 1000 kg
Height (h) = 110 m
Acceleration due to gravity (g) = 10 m/s²
Potential energy (PE) =?
The potential energy of the roller coaster can be obtained as follow:
PE = mgh
PE = 1000 × 10 × 110
PE = 11×10⁵ J
Therefore, potential energy of the roller coaster is 11×10⁵ J

Answer:
25N
Explanation:
soln:
given,
mass(m)=0.5kg
acceleration(a)=50m/s^2
force(F)=?
we know,
F=m*a
or,F=0.5*50
•°•F=25N
Speed is a derivation of energy (thats what my science teacher said)
Answer:
3.75m/s²
Explanation:
g= GM/r²
For planet 1
= GM/r² (i)
= 15m/s²
for planet 2
radius= 2*r= 2r
g= GM/r
= GM/(2r)²
= GM/4r²
= GM/r² *1/4
from (i)
= *1/4
= 15/4
= 3.75m/s²
