Answer 1

Hi. Question in incomplete. It must be like this,

Question ⇒ A ball of mass 100 g is projected vertically upward from the ground with a velocity of 49 m/s making an angle of 45° with the horizontal. Find the Maximum Height reached and the Time of Flight. ???

Solution ⇒ Mass = 100 g. = 0.1 kg.

Speed (u) = 49 m/s.

θ = 45°

∵ H = u²Sin²θ/2g

⇒ H = (49)² × (1/√2)²/20

⇒ H = 60.025 m.

Now, T = 2u Sinθ/g

⇒ T = 98/10√2

⇒ T = 0.82 seconds.

Hope it helps.
