Answer:
Weight in planet X = 0.413 N
Explanation:
Weight = Mass x Acceleration due to gravity.
W = mg
Mass, m = 100 g = 0.1 kg
We have equation of motion s = ut + 0.5 at²
Displacement, s = 10 m
Initial velocity, u = 0 m/s
Time, t = 2.2 s
Substituting
s = ut + 0.5 at²
10 = 0 x 2.2 + 0.5 x a x 2.2²
a = 4.13 m/s²
Acceleration due to gravity, a = 4.13 m/s²
W = mg = 0.1 x 4.13 = 0.413 N
Weight in planet X = 0.413 N
Answer:
0.0552 m/s²
Explanation:
Given:
Δx = 69.0 m
v₀ = 0 m/s
t = 50 s
Find: a
Δx = v₀ t + ½ at²
69.0 m = (0 m/s) (50 s) + ½ a (50 s)²
a = 0.0552 m/s²
<u>Answer</u>
part 1) 3.746 m/s²
Part 2) 0.6096 m/s²
<u>Explanation</u>
Acceleration is the rate of change of speed.
It is calculated as follows:
Acceleration = Change in speed/change in time
a = (v - u)/t
Part 1
1mi/h = 0.44704 m/s
60 mi/h = 60 × 0.44704
= 26.8224 m/s
210 mi/h = 210 × 0.44704
= 93.8784 m/s
a = (93.8784 -26.8224 )/(20 - 2.1)
= 67.056/17.9
= 3.746 m/s
Part 2
1mi/h = 0.44704 m/s
255 mi/h = 255 × 0.44704
= 113.995 m/s
a = (113.995 - 93.8784)/(53 - 20)
=20.1166/33
= 0.6096 m/s²
