Solution:
To find the acceleration,
a =
= 2 m/s2
To calculate the initial velocity at t=1:
v=u + a
10=u+a(4-1)
Put a = 2 m/s2
u= 4 m/s at t=1 sec.
PhysicsThe velocities of a body moving along a straight line with constant acceleration are 10 m/s at t=4s and 20 m/s at t=9s. The velocity of the body at t=1s is:
