<span>The initial velocity of the bike was 1.67 (vf)m/s. This is found by evaluating 7.5/4.5 which yields the velocity per unit of time which is equivalent to initial velocity.</span>

Answer:
The vehicle with the most mass
Explanation:
Momentum is the quantity of motion in a body and it is dependent on its mass and velocity.
Momentum = m x v
m is the mass
v is the velocity
Now,
Both mass and velocity are directly proportional to momentum. Since the two bodies moves with the same velocity, the vehicle with the most mass will have the greatest momentum
Answer:
Explanation:
Area A of the coil = .1 x .1 = .01 m²
no of turns n = 5
magnetic field B = .5 t²
Flux Φ perpendicular to plane passing through it.= nBA sin30
rate of change of flux
dΦ/dt = nAdBsin30 / dt
= nA d/dt (.5t²x .5 )
= nA x 2 x .25 x t
At t = 4s
dΦ/dt = nA x 2
= 5x .01 x 2
= .1
current = induced emf / resistance
= .1 / 4
= .025 A
= 25 mA.
