48 km/hr. Because the trains speed remains constant and is unaffected to Dave’s speed and Dave’s speed will remain relative to the trains speed. Taken that, when Dave is moving 0 km/hr he is moving at 42km/hr. So his speed must only add to that.

Answer:

31.55 m/s

Explanation:

Let the initial velocity of the arrow is u metre per second.

Angle of projection, θ = 40 degree

range = 100 m

Use the formula for the range.

$R = \frac{u^{2}Sin2\theta }{g}$

100 = u^2 Sin(2 x 40) / 9.8

100 x 9.8 = u^2 Sin 80

u^2 = 995.11

u = 31.55 m/s
