Momentum = mass * velocity

p = mv

p = 1.5 kg * 40 ms^-1

p = 60 kgm/s

To find components of a vector:

px = p * cos(theta)
px = 60 * cos(30)
px = 51.96 = 52 (rounded to two significant digits)

py = p * sin(theta)
py = 60 * sin(30)
py = 30

He initial momentum is 60kgm/s
The horizontal component is 52 kgm/s
The vertical component is 30 kgm/s

Elle is playing with a ball in a bus that moves in a straight line with constant velocity. What can you say about the motion of
kramer
Given that they are all on the same bus that is travelling in a straight line at the same velocity, when Elle throws the ball directly upwards, the ball will simply fall back to her. This is because the bus, Elle, and the ball are all travelling in the same direction and at the same speed. Among the choices, the correct answer is A.
