Question

A speedboat starts from rest and accelerates at 2m/s^2 for 7s. How far did the boat get? Provide numerical answer and units respectively.

Answer 1

Given:-

• Initial velocity of speedboat = 0m/s

• Acceleration of speedboat = 2m/s²

• Time taken = 7s

To Find:-

• The Distance Covered by boat.

Formulae used:-

• s = ut + ½ × a × t²

Where,

• s = Distance
• u = Initial velocity
• a = Acceleration
• t = Time.

Now,

→ s = ut + ½ × a × t²

→ s = 0 × 7 + ½ × 2 × (7)²

→ s = 0 + 49

→ s = 49m.

Hence, The Distance Covered by the speedboat is 49m.

MORE FORMULAE:-

• v = u + at

• v² - u² = 2as
