Answer:
0.203 kN
Explanation:
203 N *(1 kN/1000N) = 0.203 kN
Answer:
10 m/s
Explanation:
= Mass of arrow = 1 kg
= Mass of apple = 2 kg
= Initial Velocity of arrow = 30 m/s
= Initial Velocity of apple = 0 m/s
= Velocity of combined mass
For elastic collision
Final velocity of apple and arrow after collision is 10 m/s
Answer:
E = 1.25×10¹³ N/m²
Explanation:
Young's modulus is defined as:
E = stress / strain
E = (F / A) / (dL / L)
E = (F L) / (A dL)
Given:
F = 10 kg × 9.8 m/s² = 98 N
L = 1 m
dL = 10⁻⁵ m
A = π/4 (0.001 m)² = 7.85×10⁻⁷ m²
Solve:
E = (98 N × 1 m) / (7.85×10⁻⁷ m² × 10⁻⁵ m)
E = 1.25×10¹³ N/m²
Round as needed.

</h2>
Explanation:
Let , be the horizontal and vertical components of velocity.
Question a:
Horizontal component of velocity is the ratio of range and time of flight.
So,horizontal component of velocity is
So,
Question b:
Time of flight=
So,
Maximum height is given by
So,maximum height is
Question c:
The vertical velocity is already calculated in Question b.
