Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFMass of body (m) = 50 kg
Acceleration (a) = 8 m/sec2
Time (t) = 15 seconds
According to kinematics equation, assuming acceleration is constant,
S = u t + 1/2 a t2
Where
S = Distance travelled by the body (m)
u = Initial velocity (m/s)
a = Acceleration (m/s2)
t = Time taken
As body starts from rest u = 0 i.e. Initial velocity.
S = 0 + (1/2) × 8 × 152 = 900m
S = 900 metres
Distance is 900 metres.Last updated on Jan 30, 2025
