Exam 1 Problems

Two steel balls, one of which weighs twice as much as the other, are dropped off the roof of a building. Neglecting air resistance, which ball experiences the greater acceleration?

both balls have the same acceleration

Two identical balls, one blue and one gold, are thrown horizontally off a cliff at the same time. The blue ball is thrown with an initial velocity that is twice that of the gold ball. Which ball hits the ground first?

both balls reach the ground at the same time, but with different speeds

A projectile is fired with an initial velocity of v0 at an angle with respect to the horizontal. Assume that the positive y-direction is upwards. What is the acceleration of the projectile when it reaches the peak in its trajectory?

-9.8 m/s²

You throw an object up into the air at an angle of 60° with respect to the horizontal. After the object leaves your hand, where is the horizontal acceleration greatest?

there is no acceleration
