Question 1
Which of the following represents the correct base SI units for Planck's constant, $h$?
Correct Answer:
kg m^2 s^-1
Question 2
A motorist travelling at a steady speed of $25\text{ m s}^{-1}$ sees an obstruction on the road. If the driver's reaction time is $0.60\text{ s}$ and the vehicle decelerates uniformly at $5.0\text{ m s}^{-2}$ after the brakes are applied, what is the total stopping distance?
Correct Answer:
77.5 m
Question 3
A projectile is launched from horizontal ground with initial speed $u$ at an angle $\theta$ to the horizontal. If the maximum height reached $H$ equals one-quarter of the horizontal range $R$ ($H = \frac{1}{4}R$), what is the launch angle $\theta$?
Correct Answer:
45°
Question 4
A ball is projected horizontally at $20\text{ m s}^{-1}$ from the top of a cliff of height $45\text{ m}$. Taking $g = 10\text{ m s}^{-2}$ and neglecting air resistance, what is the speed of the ball just before it strikes the ground?
Correct Answer:
36 m s^-1
Question 5
A block of mass $4.0\text{ kg}$ rests on a rough plane inclined at $30^\circ$ to the horizontal. If the coefficient of static friction between the block and the plane is $\mu = 0.70$ and $g = 9.8\text{ m s}^{-2}$, what is the magnitude of the frictional force acting on the block?
Correct Answer:
19.6 N
