Answer:
d.20760 J
Explanation:
We are given that
Mass of cart=m=100 kg
At the top,h=22 m
Amount of energy convert into heat due to friction=E=800 J
We have to find the kinetic energy at the bottom of the ramp.
Potential energy drop=mgh=
Kinetic energy at the bottom=Potential energy drop-energy lost due to friction
Kinetic energy at the bottom =(21560-800) J
Kinetic energy at the bottom=20760 J
Hence, the kinetic energy at the bottom of the ramp=20760 J
d.20760 J
Horizontal force is applied to the object causing the spring to stretch. the acceleration of gravity is 9.8 m/s
Work done = fore × distance
wd= 47N ×o.25m
wd= 12.22Nm
(1) 2m/s²
(2) 10 m
Explanation:
(1)
To calculate acceleration we use the formula below;
a = Δ V / Δ t where;
a = acceleration
v = velocity
t = time
Δ v = v₂ – v₁
a = (10 – 0) / 5
a = 10/5
= 2m/s²
(2)
To find distance we’ll use the formula below;
½ a * t² = x, where;
a = acceleration,
t = time, and
x = distance
We are given t as 10s and acceleration is 2ms⁻², so;
x = ½ * 2 * 10
x = 10 m
