A caterpillar starts travelling at a speed of 1 m/h. If the rate at which the speed changes is 0.1 m/h^2, what is the final speed after 10 Hrs?

(a) 2 m/h

(b) 1 m/h

(c) 0.5 m/h

(d) 5 m/h

This question was posed to me in my homework.

Asked question is from Kinematic Equations for Uniformly Accelerated Motion in chapter Motion in a Straight Line of Physics – Class 11

Correct option is (a) 2 m/h

Explanation: We can use the first equation of motion here. The first equation says, v = u + at, here, u = 1 m/h, t = 10 Hrs, a = 0.1 m/h^2. On putting all the values in the equation, we will get v = 2 m/h.
