Answer:
a) The car’s speed just after leaving the icy portion of the road is the first part
Explanation:
A) F1/A1=F2/A2
F2 = 12000 Newtons, while F1 = 400 Newtons and area A1= 6 cm²
400/6 = 12000/A2
A2 = (6 × 12000)/400
= 180 cm²
b) How long does this lift the car
d2 =F1/F2×d1
= (400/12000)× 20
= (1/30)×20
= 20/30
= 0.67 cm
This lifts the car a distance of 0.67 cm
Answer:
Ans is 200 J
Explanation:
Given: Force = 20N
Distance = 10m
Work done = Force * displacement
= 20 * 10
= 200 J
By using the equation speed = distance/time we can solve for distance. The speed is 4 m/s and the time is 12 seconds. We need to rearrange the equation to Speed * Time = distance. 4(12) = 48; 48 = distance. The cliff is 48 meters high.
