Question 1
A car accelerates uniformly from rest along a straight road at a = 2.5 m/s² for t = 8 seconds. What distance does the car cover during these 8 seconds?
Correct Answer:
80 m
Question 2
A body of mass m = 4 kg is pulled horizontally along a flat surface by a force F = 20 N. If the coefficient of kinetic friction between the body and the surface is mu = 0.25 (take g = 10 m/s²), what is the acceleration of the body?
Correct Answer:
2.5 m/s²
Question 3
A projectile is launched with an initial velocity v0 = 20 m/s at an angle theta = 30° above the horizontal from ground level. Taking g = 10 m/s² and neglecting air resistance, what is the maximum height H_max reached by the projectile?
Correct Answer:
5.0 m
Question 4
A 0.5 kg ball moving with velocity v1 = 6 m/s collides head-on and elastically with a stationary ball of mass 1.0 kg. What is the velocity of the 1.0 kg ball immediately after the collision?
Correct Answer:
4.0 m/s
Question 5
A spring with stiffness k = 400 N/m is compressed by x = 5 cm (0.05 m). What is the potential energy stored in the compressed spring?
Correct Answer:
0.5 J
