Question
please help with 85 and 86 i’m thinking it’s either option one for both or option two for both but idk pls be correct
85. Projectile A is fired with velocity v at an angle of 30.° above the horizontal. Projectile B is fired with velocity v at an angle of 40.° above the horizontal. Compared to the magnitude of the horizontal component of v at the time projectile A is fired, the magnitude of the horizontal component of v at the time projectile B is fired is (2) larger (1) smaller (3) the same 86. A projectile is launched at an angle of 60.° above the horizontal. Compared to the vertical component of the initial velocity of the projectile, the vertical component of the projectile's velocity when it has reached its maximum height is (1) smaller (2) larger (3) the same 87. A projectile is launched at an angle of 30.° above the horizontal. Neglecting air resistance, what are the projectile's horizontal and vertical accelerations when it reaches its maximum height?
