Answer:
The distance of fly travel is 115.06 m.
Explanation:
Given that,
Distance = 115 mm
Speed = 1.10 m/s
Speed of fly = 2.20 m/s
We need to calculate the relative speed
Using formula of relative speed
Put the value into the formula
We need to calculate the time for the two steamrollers to meet each other
Using formula of time
Put the value into the formula
We need to calculate the distance of fly travel
Using formula of distance
Put the value into the formula
Hence, The distance of fly travel is 115.06 m.

Answer: momentum = 6kgm/s
Explanation:
given that the baseball pitcher is at stationary position, his velocity will be equal to zero. If velocity is zero, his linear momentum will therefore equal to zero.
Linear momentum is the product of mass and velocity. Given that the baseball has
Mass M = 0.15 kg
Velocity V = 40 m/s
Momentum = MV
Momentum = 0.15 × 40 = 6 kgm/s
Answer:
Option C
Explanation:
given,
velocity of airplane = 80 m/s
angle with the horizontal = 15°
speed of the ground= ?
when the plane is taking off the horizontal component of the velocity is v cosθ
so,
ground speed of the airplane is =
=
v = 77.27 m/s
horizontal velocity of the air plane comes out to be 77.27 m/s ≅ 77 m/s
so, the correct option is Option C
